Dell Latitude 7480 - crackling sound from the speakers

Question: Dell Latitude 7480 - crackling sound from the speakers

Further to my previous post about the issue with Dell Command Update tool (it keep suggesting to download and install the same drivers over and over, although I have installed them more than 5 times), I also have an issue with the speakers built-in the machine.
From time to time, while I'm listening to music I hear a crackling sound from the speakers. According to the Dell Command Update tool, I have the most updated audio driver. I even reinstalled the audio driver by removing it from the device manger and restarting the machine, but to no avail.
OS: Windows 10 pro
Audio drivers:
Speakers/Headphones (Realtek audio): 10.0.14393.0 (driver date: 15-Jul-16)
Realtek audio: (driver date: 8-Nov-16)
Any idea?
p/s. Latitude 7480 has too many hardware/software issues. I got the laptop only two weeks ago, and this is the third issue I have. I'm considering returning it back to Dell :-\

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Tx155I'm considering returning it back to Dell :-\
If you want to return it, don't wait too long. After the brief return period, which starts from the invoice date, you won't be allowed to return it.
Try the Windows native audio driver -- as a test.
1. Open the Device Manager.2. Expand the "Sound, Video & Game Controllers" section.3. Right click on "Realtek High Definition Audio" and select to uninstall.4. Put a check mark in the option to delete the driver software, and then ok.5. Restart the laptop and go back to the Device Manager and check again for a Realtek driver. Keep uninstalling & restarting until Realtek no longer appears under Sound...Controllers and "High Definition Audio Device" appears in its place. "High Definition Audio Device" is the name of the native driver.
[The reason you might have to go through the process more than once is because the driver files for more than one Realtek driver could be on the hard drive. When a Realtek driver is removed, the next one gets installed if Windows can locate the files. Windows installs its generic driver only after all Realtek files have been removed.]
To re-install the Realtek driver, it's better to download it from your Dell support page rather than letting Windows Update find one.

A detailed review of the Latitude 7480 notes the laptop has a very noticeable coil whine when the SSD is accessed or background processes are active, and there are several posts on this support forum regarding speaker crackling. Have both of these issues been fixed on new Latitude 7480s?

Hello all,
I have a question about Dell Latitude 7480: Can I install a SSD M.2 NVMe into DELL Latitude 7480? 
I intend to buy this laptop and a SSD 512 GB NVMe for it.Just want to make sure because as I see in Dell latitude Laptop Specification, latitude 7480 's hard drive is "M.2 128GB SATA Class 20 Solid State Drive"Hope to see your reply soon.Thanks

Answer:Is Dell Latitude 7480 supported SSD M.2 NVMe?

The Specifications section of the Owner's Manual on frustratingly doesn't say anything at all about the M.2 connector (it isn't even mentioned as existing in the system!), but at least in the Dell US store, the 7480 has an option for "M.2 512GB PCIe NVMe Class 40 Solid State Drive" -- so yes, the 7480 does support NVMe, and choosing that option does NOT force you to choose the Thunderbolt 3 motherboard option, for what it's worth.

I have already tried twice to format window, uninstall sound drivers and only keeping High Definition Audio native driver only but the problem is not getting rectified. I shown my Laptop to a Mechanic also and he said speakers are ok. So the problem is with Software but yet I am not sure about where is this problem in Software or Hardware? I have also done diagnostic test but everything fine in Test. Please help me with this problem, I am unable to listen music and watch movies. Your Help will be highly appreciated.

Hey all, I recently got a new laptop, dock, and monitors at work and am having issues with the 3rd monitor. Model are as follows:
1 - Dell Latitude 7480
1 - Dell D6000 Dock (2 Displayports, 1 HDMI port)
3 - Dell E2318H Monitors (Displayport and VGA input only)

The D6000 dock has 2 display port ports, as well as 1 HDMI. I can run 2 of the monitors successfully on the displayports, but cannot find a cable that will allow me to use the 3rd monitor with the HDMI port. I have tried restarting multiple times with lid closed, and also rebooting the dock by disconnecting the power.

I have tried both of these with no success:
HDMI to Displayport cable.
HDMI to active VGA adapter to VGA cable. (Adapter is a Startech HD2VGAE2)

FYI, when using the dock with an HDMI to DVI cable and older monitor, it recognizes the 3rd monitor correctly after rebooting the dock.

After installing Windows updates and Dell's updates, including the "Dell Data Protection" software, the fingerprint login option ceased working.
I tried configuring the fingerprint login via the DDP Console, but in the end of the process (after configuring the fingerprint) it says that "The biometric unit is not in the proper state to perform the specified operation". What does it mean?

It is worth noting, that the biometric device reads fingerprints (I'm able to add\remove fingerprints via the Windows sign-in options screen and via the DDP Console, until it says that there is an error as stated above).

It seems that I have a problem with the Dell Command | Update tool, because it keeps suggesting to download and update the same 3 updates all the time - please find enclosed a print screen. I already installed them at least 3-4 times, but nothing helps.. By the way, it didn't find the new BIOS version which I had to download manually.
While when I run the "detect drivers" tool via Dell's website, it doesn't find any new drivers to be installed. However, I suspect that it just doesn't work well, because manually I found several drivers available on Dell's webpage which were newer than the drivers which are currently installed on my machine (I logged in with the laptop's service tag, so I believe that only relevant drivers should be presented).
My machine is Dell Latitude 7480 running Win 10 Pro.
Please advise.

Hi Guys
I am not able to install the correct Video driver for my Latitude 7480.
This laptop came with Windows 10, but in my company we need to downgrade to Windows 7 Enterprise.
After I did the downgrade, the only driver I was not able to install was the video. (Intel-HD-Graphic-500-P500-series-D5Kd6_win21_20.16.4627_A02.exe)
I saw that the driver in Windows 10 appear as follow Intel(R) HD Graphics 620, but even in the Intel web page I could not find the driver.
I hope somebody can help me to find the correct driver
It is for Windows 7 Enterprise 64 bits version.

I have just bought a Dell Inspiron 15 7559 and it just arrived this morning. However, when I try to play any sound the speaker starts to crackle heavily. The only solution that works is plugging in headphones and unplugging them which seems to work. But once you shut down the computer, and turn it back on, this problem still exists. I have already updated the realtek hd audio driver as well as the bios. I would hate to have to return the laptop as it works flawlessly otherwise.

Answer:Crackling sound from speakers on HP Pavilion

Hi @emmikatarina , Welcome to the HP Support Forums!   I understand that you are getting a crackling sounds coming from the speakers of your HP Pavilion Notebook PC. I will try my best to help you with this issue. Here are some instructions from SuperMario1 on how to resolve this. 1. Go into Control Panel, then Sound.2. Under the Playback tab, double click on Speakers to open Properties. 3. Go to Advanced tab. In the drop down, select the highest quality stereo output. 4. Click Apply and close all windows. If that didn't help, then here's round 2: 1. Instead of the Playback tab, go to the Recording tab. 2. Double click on Stereo Mix. 3. Go to Advanced tab, and select highest quality from the drop down. 4. Click Apply and close all windows. These steps should be enough to resolve the issue. If not, I would recommend a System Restore next, if the issue began recently. I want you to bring the computer back to the earliest restore point possible, in an attempt to dodge whatever caused the issue. Here is a document on how to perform a System Restore: System Restore If the issue is not yet resolved, then please answer the following: 1. Does this issue only occur on online videos (to be certain, test something using Windows Media Player)? If so, is it only YouTube (to be certain, play a video from another site)? 2. Do any other devices in your house behave this way when you are streaming music?... Read more

I am having problems with a set of computer speakers. They make a crackling sound when the volume is turned up. I don't seem to notice the noise when the speakers are turned way down. The volume setting in the computer are set at half and I have tried another set of speakers and they too make the same noise. The computer is a 2 year old HP using windows xp as the operating system.

Any help or insight anyone one might have on this would be greatly appreciated. Thank you

You'll get that when the audio driver is corrupted or if another device is on the same IRQ.

Good day,

before of you read, sorry for my bad english :D

ok, i have the old pc HP Compaq 6735s oldiest model and have problem.. I have the headset Plantronics .Audio 655 DSP... Its USB (no Jack) headset, but sound is crackly and randomly.. Microphone is good, no problem, also speakers... I tested in another pc, and work correctly (Win 7), also in WIN XP not installed drivers.. I telled the makers of headset and reply is here:


So in the Windows 8 now it does not work? It was not an XP as I said? In that case it is most likely incompatible. Think about that the headset is made years ago while Windows 8 just released. Contact Microsoft and check if they have any updates to the USB drivers that will be able to use older USB devices?

I tested reinstall USB drivers, not work.. I tested install sound drivers, but for Win 8 not found...

Answer:Windows 8: Speakers have crackling sound

Hello GAMELASTER and welcome to TSF,

Your USB headset does not rely on the Audio chipset.

The Plantronics website touts it as not needing software... I can't find any issues similar to yours by searching the WWW, so I have no base to work from.

Just so I am clear... You are running Windows 8 on a Compaq 6735s?

Try using a different USB port.

Have you had any other issues since upgrading to Windows 8?

I have an HP Pro4510s Laptop for around 4 years now. Everything is just fine with this laptop but recently, about 1 week, I have got some issue with the sound.

There's a crackling sound from the speakers and it's very annoying.

I have searched for hours on goggle how to fix it, but in vain.

I have uninstall and install SoundMax again. Downloaded the audio drivers for Hp website.

Nothing has resolved the issue.

What makes it weird is that when I connect my Nokia bluetooth headset to the laptop, I can listen to music and watch movies with some crystal clear sound, NO CRACKLING sound!

But as soon as I disconnect the Bluetooth headset, the problem comes up again.

I would really appreciate some help.

Thanks guys.

Answer:HP Pro4510S Crackling Sound in speakers

Sounds like the speakers or the audio chipset output to the speakers is faulty. It's possible for it to function properly on one output and not the other.

Hi All,

I've recently just purchased a new P100 - 160 and on the whole I'm chuffed to bits with it.

However, there's one thing that's really bugging me... and that's the sound quality.

When I purchased the laptop one of the selling points was that it had "Harman/Kardon" which are supposed to be really, really good. Now, from a 3D / Surround sound point of view, I've got to say that they certainly seem to live up to what I was told.

However - In terms of "volume capability" the speakers seems not to give the maximum.... and I'm not talking about having the volume so high that the neighbours can here it either!

Turn the speakers up more than about 1/4 of the way, and the sound/speakers crackle very mad - especially when it's playing anything with even a slight bit of bass.

I've tried changing the equalizer and volume settings in Media Player but that didn't help either.

Has anyone else had this problem, or does anyone know what the fix may be?


Answer:Crackling sound from speakers on Satellite P100-160

You?re right.
The notebook is definitely delivered with Harman/kardon speakers and usually such speakers are also known as "good quality" speakers.
Therefore I have investigated a little bit in this forum for similar issues and found this link to the Toshiba document about crackling noise on Satellite P100.

It seems the BIOS and driver update should be done.
One tip: You could try to remove the old sound driver files before install the new one.

good luck

Hey guys, I just reformatted my computer because I had major spyware on it that I thought was causing computer freeze which then causes a crackling sound from my speakers. It was happening at most every 20 minutes. Turns out it is still happening sometimes. It seems to happen when I'm doing something that uses alot of RAM. It happened twice while trying to install the demo of F.E.A.R. and then again when I was watching Batman Begins on my computer.
The computer freezes and instantly emits a crackling sound out of my speakers. Does that sound like anything to anyone?

I have an HP ENVY 15t-j100 Quad Edition CTO Notebook PC. The oddest thing happened the other day, I didn't drop my laptop or do anything out of the ordinary to it. One minute the speakers are fine, the next minute there is a frequent popping or crackling sound coming every 20 seconds or so, even while using headphones.
I tried uninstalling and reinstalling the driver from the product website to no avail.

However, there is this one driver that always has a yellow exclamation mark on it called the "High Definition Audio Device". It would make sense that this driver is the culprit but its been yellow for a month now without any popping or crackling sound and it is absolutely impossible to resolve it. I completely uninstalled and re-installed my sound drivers and that didn't fix it and windows troubleshooter can't find the driver either.

I'm at a loss here guys. I don't want to have to replace the speakers on a one year old computer but I might have to. Thank you in advance for any help I can get.

Hi everyone,

Not sure if this is the right place to post this, so please feel free to re-direct if necessary.

I have a brand new Toshiba Satellite A665-S9092 laptop that just started exhibiting a weird problem: I get an occasional crackling, popping sound from whatever I plug into the headphone jack. I've tried with my Bose speakers and two separate sets of headphones. It seems to occur whenever the hard drive is accessed: when the computer is idle, I don't hear a peep, but whenever I e.g. refresh my browser or open a program, it starts crackling. The odd thing is that I don't get this from the built-in laptop speakers - only from whatever I plug into the headphone jack.

Anyone have any idea what could be causing this? One of the main uses of this machine is playing music so this problem is putting a serious crimp in my enjoyment...

(Extra info: under "Sound, Video and Game Controllers" in the Device Manager I have 4 instances of nVidia High Definition Audio, and 1 instance of Realtek High Definition Audio. Checking "driver update" tells me the drivers are up to date. Not sure why there are 4 instances of the nVidia HD Audio.)

Hi there.

I have just purchase a new laptop (L650-OED) which is running windows 7 - 32 bit.

The in-built speakers make a crackling noise and only work intermittently. When you adjust the volume up or down they work for a few seconds and then cut out.

I have tested the sound through the headphone jack which is working perfectly. I have also reinstalled the device driver (Conexant HD Audio but it has not made any difference.

Is there anything else I can try or is this a warranty issue?

Appreciate any advice.


Answer:Satellite L650-OED In-built speakers crackling and intermittent sound

>I have tested the sound through the headphone jack which is working perfectly.
Hmm?. for this would mean that this has nothing to do with the sound card or with the sound driver but with the faulty speakers.

Therefore I recommend asking an technician for an notebook check? possibly the speakers needs to be replaced. If warranty is valid, then everything should be done free of charge.

Hey Guys...

So my Packard Bell Easy Note MX37-S-200 has suddenly started making persistent " Crackling " and " Popping" noises from the moment I boot it. The noise is coming from the speakers and the sound is now distorted. I have very recently got it back from the repair shop after having my AC jack replaced... I would really like to rule everything out before I start pointing fingers at the repair guy

Things I have tried - Disabling sound driver - Noise was still there and laptop just installed it again.

Running avast scan through it - Scan picked up nothing.

Played with the sound setting - Nothing changed noise still there.

Plugged in PC speakers - Noise still coming from laptop but sound came out of the speakers fine.

I have noticed also that when the laptop first starts up the noise is louder and more spaced out. I'm wondering maybe whether it is the fan? But I don't no why the noise would be coming from the speakers.

Would really appreciate any help
Thank you

Answer:Crackling noise coming from laptop speakers + sound distorted

My guess is that based on the information provided that the wires for the speakers have either been damaged or crossed in some way where they are touching something they shouldn't causing distortion. My advice would be to take it back and tell them whats going on and make sure to have them fix it for free if they opened it and caused this problem.

Answer:Headset will not be recognized Latitude 7480

You should have an option for just a regular Headset, but even if you have a non-Dell headset, you should still be able to use the "Dell Headset" profile.  Can you include a screenshot of the pop-up you're seeing?  That's an important step because that's how you tell the driver how to configure the audio jack properly for the type of device you plugged in.

Howdy, all!
Has anyone had any issues with getting BitLocker working without prompting for recovery within Win10 on this model? We purchased several 5480s and 7480s, and both models initially experienced issues where BitLocker would successfully enable and encrypt, but would prompt for the BitLocker Recovery Key at every boot. I was eventually able to get the 5480 models working by using the in-the-field downgrade to TPM 1.2, along with the 1.3.2 BIOS update, which specifically addresses "Win7" (i.e. TPM 1.2) BitLocker problems.
Try as I might, I can't find any combination of things that work with the 7480. Our imaging and boot sequence currently requires enabling Legacy ROMs in BIOS, and while we have plans to enetually move towards a straight UEFI boot sequence, it's going to require a pretty significant procedural change that we are NOT poised for right now. I noticed that there is not yet a 1.3.x BIOS revision available for the 7480, and that was the final piece of the puzzle eventually did the trick on the 5480 model. Does the 7480 suffer from the same problem, and is still pending a firmware fix? Or am I battling another problem altogether with the 7480 series?
Any information the community can provide will be helpful!

Hi All,
We have recently started ordering the Latitude 7480 Business laptops and seem to be having issues with Bitlocker passing the key to the TPM Chip.
We are building with Win 10 Enterprise image so BIOS is set to Legacy Boot rather than UEFI, but TPM is both ON and Enabled.
When we try and enable BitLocker it asks to restart the machine, on next boot in there is an error "BitLocker could not be enabled. The BitLocker encryption key cannot be obtained from the Trusted Platform Module (TPM). C:\ was not enrypted"
Doing some looking online seems there was a forum post on here just recently about the same issue and the issue was resolved by Dell releasing a new Firmware (V 1.3.3) for the devices which corrected the issue in TPM 1.2 - however these devices come with TPM 2.0, I have installed the latest firmware from their site (which is now V 1.4.6 which also includes a security patch for the Intel AMT system) but this still gives the same error.
Any suggestions?

It's a new Dell and it has been making crackling sound since I got it.
I spent an hour on the phone with a technician who restored the laptop with Windows 8.1 to an earlier point in time and it stopped crackling for the rest of the day, but the next day, the noise was back.
The worst are "ding" sounds, they have more crackle than ding. Video playback is bad but at least we can understand what is said. Youtube is bad. mp3 audio is bad. Crackle is there with earphones too.

Answer:Dell Inspiron 11 (3147, Mid 2014) makes crackling sound whenever sound is played

lelouIt's a new Dell and it has been making crackling sound since I got it.
Hello. If it made the noise right out of the box you probably should have returned it as defective during the brief return period. 
Does it make the noise only when running on battery power or also when plugged into house current?

Hi Dell Community,
As some of you know, the traditional Dell docking stations (aka E-Port Replicators) switched to the TB16 and other similar types. I only have 1 TB16 docking station that arrived so I don't know if it's defective. Basically I cannot get it to work with the 7480 and I'll add the info below. Any suggestions would be appreciated. The laptop only detects the power coming from the TB16, nothing else.

- OS Windows 10 Enterprise 64-bit
- I followed the steps on the Dell Knowledge Base [How to Use and Troubleshoot the Dell Thunderbolt Dock (TB16)
- Under Dell Thunderbolt Dock TB16 Manual Driver installation, there is no Intel Thunderbolt Controller Driver or Intel Thunderbolt 3 Firmware Update under Chipset. 
- I've updated everything else
- BIOS: initially the Thunderbolt Adapter Configuration settings were all unchecked and greyed out. I performed  a BIOS reset to factory settings and now it is still greyed out but now [x] Enable Thunderbolt Technology Support is checked. Even before and after it was checked, the TB16 still did not work.
Some techs online wrote that they had to remove the CAB files in their Windows 7/10 images and had to follow the manually TB16 install (9 steps) as a workaround. The TB16 specs confirms that it is compatible with the 7480 model.
Has anyone else encountered this problem? Is this a driver issue that we're waiting for Dell to fix or should I return the TB16 docking station back to Dell as defective?

Answer:TB16 New Dock with Latitude 7480 not working

You definitely need the Thunderbolt software installed on the PC, and the 7480 recently got a Thunderbolt firmware update.  Both are listed at if you just select Latitude 7480 > Drivers and Downloads > Find it myself > Windows 10 64-bit.  However, sometimes entering your actual Service Tag can filter out some updates that are applicable to your system, which is why I always specify only the model.

Hi.I'm new to this forum, so please forgive me if this question has already been asked.
I have a problem with the WD15 dock together with the Latitude 7280/7480 series.
The problem is that a keyboard connected to the dock does not work in pre-boot.So I won't be able to for example enter "bios" with help of the external keyboard, and even worse (for the users in my orginazation anyways) enter the Bitlocker PIN with the external keyboard.
My bios version is 1.0.8.
I have tried both the USB 2.0 and the 3.0 ports on the dock.I have tried disabling Fast Boot in bios.Tried disabling Thunderbolt (since the keyboard is working on a 5480 laptop, I figured that this might be the problem).I have also tried enabling Thunderbolt Pre-boot modules, and Thunderbolt adapter boot support in bios.None of this actually helped.

If I connect the keyboard directly on the laptop it's working.
Hopefully someone here has some kind of idea what might be the problem.According to Dell support the keyboard should work in pre-boot when connected to the WD15 dock.

A reboot fixes it for awhile then it starts all over again.  This problem coincided with a recent round of updates, though the touch-pad driver was not one of those updates.

This issue has been driving me nuts and I was wondering if anyone has been able to resolve this successfully.
The laptop is not docked (at home) but connected to AC power. I close the lid and reopen the lid after a few minutes. But the screen has gone blank and the laptop does not respond to any keystrokes. So I pretty much have to resort to rebooting. Note that this does not happen always but happens once every 3-4 times.
I have searched the internet and tried everything - disable Intel display drivers, disabling hibernate, enabling "Do nothing", "Do not sleep", etc. from Power Options, Updated BIOS, drivers,  - but nothing seems to help.
My old Lenovo running Windows 10 never had this issue. So I am not sure if this has anything to do with Windows 10 or something specific to Dell.

Hello all...
This is my first post on this forum in a desperate attempt to fix my audio problem. I have been reading forums and attempting fixes for days with no avail. I hope someone here can help me :(

For about one week now my sound has been crackling/is very distorted... After reading up on forums many people have said the main cause to this problem was a driver incompatibility issue between windows vista and dell sigmatel cards. I have attempted to try and unplug/replug in the speakers while also checking checking for a possible short along the line and found nothing. I then moved onto uninstalling the sigmatel audio driver from sound drivers as well as the high definition sound codec from my drivers menu and tried to install just about every driver I could find off the internet and nothing has worked. I read on one forum that someone uninstalled and reinstalled their ATI drivers and it worked for them so I tried this as well since I have an ATI graphics card and of course it did not work either. I run an analog out from my graphics card to my TV which I use as my main monitor, when I turn up the speakers on my tv I encounter the same distortion, this is why I'm almost positive its a software issue and not hardware. I tried playing a movie through my TV with a dvd player and it was fine, and I also played music through my speakers with my ipod and no distortion. The only time there is distortion is when Im using my computer. I am extremely frustrated at ... Read more

Can anyone help here?

I got a Dell Inspiron 1525 back in September. Runs on Vista.

A few weeks ago, I began noticing a crackling sound that was coming from the top left hand corner of the keyboard section of the laptop, right near where the 'Inspiron' logo is. It doesn't usually start until I've had the computer running for 30 minutes or so.

I called Dell and shipped the computer to their facility since it's still under warranty. They sent it back saying that they could not detect any problem with any of the hardware and therefore, did not fix anything. Sure enough, after getting it back and turning it on and being on it for 30 minutes or so, the sound is still there.

Everything about the computer works fine...the Internet, my progams. It isn't slow or anything. But this sound just doesn't sound right.

Does anyone have any ideas what this may be? Could it be an issue with the laptop's fans? If so, aren't the fans considered to be part of the hardware?

Thanks for any light anyone may be able to shed on this issue.

- Brian

Hello. Have you listened for the crackling through headphones? If the noise is not in the 'phones, only in the speaker, then probably the speaker needs to be replaced. This is particularly likely if the issue happens with both Win7 and 8, and with different audio drivers.

You can find the instructions for replacing the speaker on page 75 of the XPS L502x Service Manual.

When I listen to audio with headphones it comes out crackly and distorted, however, when I connect a speaker via aux cable in the same headphone jack it sounds normal. Audio from the laptop's speakers in normal as well. I have checked the headphones and it's not them that's the issue.  The crackling happens with all my headphones. 
The problem is very recent. A couple of days ago I picked up my headphones unaware they were plugged into my XPS. The jack was pulled out of the headphone jack when I picked up the headphones and it's been an issue ever since. I would have immediately assumed that It's a hardware thing with the jack although, I didn't pull it out very hard nor did it come out at a weird angle so I can't see how that could've of broken it. Also, the jack still works perfectly with external speakers so I'm not too sure what's wrong with it.

Last week, I purchased a Dell Precision 5510 with Windows 7 and the audio was working fine, but on Saturday night I was watching a video on Netflix when the right-side speaker started to crackle. I followed the instructions on a number of tutorials including reinstalling the RealTek audio drivers and switching to the windows default drivers, but none of these things have gotten rid of the crackling.
Of note, the crackling only starts when the audio is raised somewhere around the 50% capacity mark or beyond, but it is a constant and persistent annoyance at that point.  I am of the belief that this is a hardware issue at this point, but any insight others could provide before I contact Dell Support would be appreciated.

Answer:Dell Inspiron 15 i5577 Gaming Laptop Crackling Sound

Save yourself some time and frustration. Check and see if the speakers still crackle when not plugged in via ac power. If they sound fine when the ac adapter is not plugged  in, the problem could be the adapter. Out the box, my brand new dell sounded like garbage. I did everything, drivers, reset, etc...Finally, I just decided it wasn't a deal breaker, I would just use a bluetooth speaker. But I finally realized the only time the speaker sounded like garbage is when the ac adapter was plugged in. So I tried another one and they still sounded bad. I thought maybe I should increase the wattage so I got a 65W adapter and viola! I reset the system, plugged in the new adapter, changed the bios setting for power and it's been working like a charm. I hope that helps.

So I recently opened my CPU because it was lagging and I thought maybe a little clean up might do the trick. So I softly brushed the drivers inside the CPU to get some dust off. However, when I turned on my PC, it seems that whenever I watch videos or play games, a loud crackling sound comes out from my speakers. I don't know what is causing this.

I have tried disabling my drivers (sound and display) but to no avail. However, if I mute the volume on my sound driver, the sound disappears. Which lead me to the conclusion that it might be a conflict of sound and display.

Since the problem only occured when I opened my CPU and cleaned it, it might also be a wiring problem or something.

I have a Dell Latitude D820 laptop running Windows XP SP2. 1-2 months ago, the sound suddenly stopped on it. I don't see the volume control in the tray anymore. Any application needing sound complains there is no sound board installed.

Device Manager shows yellow exclamation marks right besides "SigmaTel High Definition Audio CODEC" and "Microsoft Kernel System Audio Device". I have tried many things:

- Uninstalling/reinstalling both
- Scanning PC for viruses (Symantec Corporate) and Spyware (Checkpoint Integrity)
- Running a Windows repair install
- Running sfc /purgecache followed by sfc /scannow
- Booting in safe mode and replacing the c:\winnt\system32\drivers\sysaudio.sys file with a file from another PC where the sound works correctly
- Setting devmgr_show_nonpresent_devices=1 and to see if there were any suspicious instances of drivers shown in Device Manager

I am now running out of ideas and would greatly appreciate any help! I am ready to run any diagnostic tools suggested and to post results in this thread as suggested by anyone. Many thanks in advance!

Go to Start>Control Panel>Sounds and Audio Devices.
On the Volume tab, make sure that the "Place volume icon in the taskbar" is checked.

I have a rather harmless question concerning an odd problem that has been occurring with the headphone jack on my Dell Latitude laptop. When I start up the computer and want to use the headphones, it works perfectly fine. I can even choose between using the speakers or the headphones interchangeably. However, the issues come in when I receive communication from microphones on other computers. For instance, when playing in an online game, the headphones will work until somebody says something using a microphone through the voice chat client. At this point, all sound exits the headphones and comes out of the speakers regardless of whether the headphones are still plugged in or not.

I can make a quick fix by restarting the computer, but then the cycle begins again. Like I said, it's a pretty harmless problem. Thanks ahead of time.

Hello. Dell does not support Windows 8, 8.1, or 10 on the Latitude E6410 model and cautions that you might lose some functionality if you do run Win10. You can see the notice on the E6410 support page.
The E6410 has IDT audio hardware on the motherboard. The IDT company went out of the consumer audio business before Windows 10 came out, so I doubt that there will ever be a Win10 IDT audio driver for that model.
You can try to use the IDT Win7 audio driver in Win10, by installing it while using Compatibility mode.
1. Download and save the audio driver to your desktop or any convenient location on the hard drive.  [There are two "formats" on the driver's page.

Answer:Dell Latitude D620 sound drivers

The drivers should be on the Dell site. What operating system are you running? You may be able to get your sound back by running Windows Update

but no luck so far. In the Sounds and Audio Devices Properties, the device volume area is greyed, so I can't adjust the volume there. I don't have external speakers, but I can't get any sound from the unit itself.

I have just recently reformated the hard drive on a Dell Latitude C810.  I had installed all of the proper drivers from the Dell site for this model.  (There is no service tag so I cannot get any help from Dell.  I have no idea why, its a third hand computer.)  All worked fine except for no sound and the touchpad won't work.  I checked settings in BIOS for touchpad and all is good.  There are no errors in the device manager.  I even bought a Latitude C810 driver restore cd and still nothing.  These devices worked fine before I reformatted the drive.  I have all the updates from windows.  I am at a loss.  Anybody have any ideas?

I am trying to use a 3rd party external GPU enclosure that attaches via thunderbolt, and when attached, I got the message pop-up that external GPU support was not enabled by the vendor, and as such the device will likely not work? Has Dell locked the Latitude 7480 down to no external GPU support?

Answer:Latitude 7480 - Thunderbolt 3 - Thunderbolt software say external GPU support not enabled?

Probably.  I read somewhere that since Dell is pushing their Alienware external GPU stuff that uses a proprietary connection, they never enabled external GPU support via Thunderbolt.

When I undock the laptop by pulling the USB-C cable out (either sleeping beforehand or not sleeping first) then I am getting an intermittent issue where the wifi claims to be disabled. The only way to resolve this is a hard reboot.
Toggling airplane mode doesn't help. Disabling and reenabling the wifi network connection doesn't help. Toggling airplane mode from Fn-PrtScr doesn't help.
It is acting as though the hardware radio is turned off (like when laptops used to come with a hardware radio switch), but with no method to turn it on again.
Looking in the system event log I can see entries from source Netwtw04, Event ID 7012 stating "radio OFF"
Drivers and bios are all up to date.

Any ideas?

Hi guys,
Apologies if this has been posted elsewhere (though I haven't been able to find anything). I'm testing a TB16 dock for use with the Latitude 7480 but cannot get it to work with the monitors. it is supplying power to the laptop, but nothing else plugged into it is recognised. I have updated all the available drivers for the 7480 and the BIOS is updated to 1.2.9.  The BIOS was updated first.
When I attempt to install the  Thunderbolt 3 Firmware update, I get an error that "No Thunderbolt controller update supported for this platform ID=0x7A0".  
I have installed the available thunderbolt drivers listed here in addition to the Thunderbolt Software
I'm running Windows 10 Pro version 1607 Build 14393.953
Short of uninstalling all the drivers and reinstalling in the right order (again), I'm running out of ideas, so any help would be appreciated.

Answer:Dell 7480 and TB16 dock

I don't know about that particular machine but the TB firmware and controller are installed to the machine before you even plug in the dock.
If the Thunderbolt options in the Bios are greyed out, you do not have a Thunderbolt controller.  I will leave it to you as to whether you have a 2 or 3 lane Thunderbolt system.

I have a Dell Latitude D630 and Windows 8. The generic Windows sound driver made the sound for the laptop run, but not with the docking station. I installed the Sigmatel drivers for Windows Vista 32bit. They also worked for me on Windows 7. First, they didn't wanna install, but then I made a BIOS update from Revision A03 to A18 and it solved the problem. Now again I have sound for the laptop, but when connected to the docking station the following happens:
When I set the normal speakers as output: Sound starts to play through the speakers connected to the docking station, but aborts quickly (for example the Windows sound when changing the volume).
When I set the SPDIF out as output: No sound at all!

The Sigmatel website obviously doesn't provide drivers since it's not existant anymore. The audio business was sold to IDT, but the IDT Website sucks: Detailed descriptions of all sound cards, but no drivers at all!

There was an IDT modded drivers section on before, but unfortunately the project is dead. I can't even find the uploaded files anymore. Anyway, one doesn't know if it works for Win 8 at all.

Audio device:


I tried the following drivers from the Dell website already which according to Windows 8 work, but give me the described sound problem:
- 2Y0VM
- R153997
- R171788
- R171789
- R218148

Any ideas how I can get this to work?... Read more

Answer:Windows 8 on Dell Latitude D630: Sigmatel/IDT sound drive

Generally, only Dell supplied drivers work properly on a Dell PC. Non Dell drivers will either not work or not work properly in most cases.

Have you tried posting on the Dell Laptop forum? That would be a good place to start.

Dear Friends,
I'm having hard time figuring out what was wrong with my laptop which default sound device could not be changed both options "configure" and "set default" are greyish and disabled . I have upgraded the driver that gives me no help. further, I have updated audio driver with Audio_Driver_RPG74_WN1.0.6454.0_A06.
Win 7 x64
Dell Latitude E6430 core i7
any help and support is highly appreciated.
thank you in advance

Answer:Default sound device is disabled - Dell Latitude E6430

Hello. Is your audio working at all? If so, what is showing as the default device? Which device are you trying to make be the default?
If the audio is not working at all, did the failure come with no unusual circumstances, or was it after a new program or operating system was installed?
If no audio at all, use System Restore to try to undo changes. Try to find a restore point dated from before the failure and revert to that date. Using System Restore will not delete any data files. Type "system restore" into the Start menu search box, and then, in the list of results, click System Restore.
If that does not help, remove the IDT audio driver and run on the Windows native audio driver. Go to Start>Control Panel. In the upper right corner select "View by category". Select "Uninstall a Program". Find the IDT audio driver then right click on it and uninstall it. When you reboot the computer Windows will install its native audio driver. Check that it is installed by going to the Sounds properties. If it says "High Definition Audio Device" on any of the tabs then it is the native driver. If it says "IDT High Definition Audio Codec" then it is still an IDT driver, so repeat the procedure. (Windows will keep installing IDT drivers until all that have been downloaded are removed.)

If still no audio at all, check the Windows Audio Service. Go to Start>Run and type "services.msc" (without quotes) then hit the 'Enter... Read more

Answer:dell speakers no sound

Did you raise the volume level in speaker mode. There is a micro switch in the headphone jack, try making and un-making this connection several times to see if maybe the switch is stuck.

This problem has been pointed out in previous posts (link above)
Dell just replaced the main board of the unit but the problem still exists.
I just also noticed that this noise issue only occurs when the main unit is connected to the keyboard dock.
When the two units are separated, this annoying noise immediately stops and I no longer hear any buzzing sound.
With that said, has anyone tried replacing the keyboard dock unit?

I doesn't seem like it's coming from CPU which is located on the top side of the main unit. This sound seems like it's coming from the very bottom of the main unit of from the keyboard unit.

Answer:Dell Latitude 7350 2in1 buzzing sound NOT fixed after repair

This exactly represents my problem: the noise seemingly stops when disconnected from the keyboard. Also, I have noticed the sound with sometimes be louder in accordance to me scrolling on the mouse pad or using the touch screen to use the scroll bar.

Hi all,

I'm trying to remove the keyboard from a Latitude D510. One of the steps is to remove the "Center Control Cover" by popping it from the right hand end. Dell say this:

1. Open the display all the way (180 degrees) so that it lies flat against your work surface.

2. Starting on the right side of the computer, use a plastic scribe to pry up the center control cover. Lift it away from the computer, and lay it aside. to expand...

But that's ALL they say!

Anyway, I started trying to lift it off carefully using a flathead jeweller's screwdriver in lieu of the plastic gadget I had which didn't seem to be working. And at one point I heard a horrible cracking sound. So is the cracking sound normal? (I found instructions for something I was doing with a Mac and they warned that the Apple instructions fail to point out that a loud cracking sound is normal and not something to worry about!) Also, can someone please give more detailed instructions of exactly how one gets this cover off, such as where to lever step by step.


Answer:Removing keyboard from Dell Latitude D510 - craack! Normal sound?


Yes lifting of that top cover does crack like hell (your poping of the holders), dont have a Dell, but did replace my KB on my Compaq laptop and thought at one point with it bending while trying to force off it would snap, best advice is to get some small flat screwdrivers and with one at the end pop another further along the cover and slowly lift that off, then move the first scredriver past the 2nd one to lift it off slowly, doing it all from one end their is chance of snapping it, so slowly moving along I find best way.

Sometimes there are videos on youtube on doing things like this but none for your model sadly.

Hello. My dell latitude D505 laptop was making a loud winding noise underneath(facing me) the left side closest to the screen. Underneath that location is a fan. Why it was making such a loud winding noise, It sounded similar to an old tape player rewinding a cassette. I don't know but I do know it's never done that before.

Does anyone know what this could be and is it safe to use my computer even though the winding noise stopped? It lasted for at least a few hours, then suddenly stopped.

Thank you.

Answer:My Dell Latitude D505 laptop was making strange winding sound

Is it warm or hot in that location? It's either the HDD or CPU Fan?
If it's the CPU Fan that needs to be replaced.
If it's the HDD then backup your data or clone the HDD as the HDD is starting to go.
Normally if it's the HDD it will make clunking noises.

We have recently received these new model type laptops from Dell in our company, but we seem to have issues trying to image them. We currently only can support UEFI boot imaging, but this particular model of laptop does not let us choose the boot order or pick the NIC manually.When I go to Legacy mode, I can boot network without issues, but on UEFI it does not let me select anything. Even trying to select the boot manager results into no choice and continues loading Windows factory installation.

Any solution to this? How can I boot to PXE while in UEFI?

Answer:Unable to boot NIC - Dell Lattitude 7280 / 7480

What operating system are you attempting to install on these?  Note that 10 is the only OS supported by seventh-generation CPUs - - you must use a 10 image to boot from.

I'm having an issue with the contents of application windows when unlocking a docked (dual display) Dell 7480 laptop, whereby the application windows appear blank after unlocking the laptop.  The OS (Win 7) is stable, and a reboot fixes it.

I have updated all drivers via the Dell website, and also the BIOS, but the issue remains.  I've moved the HDD into another laptop, same problem.
I have also tried different monitors/cables, all to no avail. 
Any help greatly appreciated.

The compatibility list for SED NVMe support states that the DDPE tools will support SED (OPAL) hardware encryption for the PM961 but I don't see the SM961 listed and I thought the only major difference was TLC vs MLC.  On the 7480 it shouldn't make a difference at 2x, but the write speeds will be much better on the SM series.
Is it compatible?  The performance of the Toshiba XG4 is unacceptable.  The PM961 would get closer, but it'd be best to retrofit an SM961.  Thank you for any help offered.
