Preferred Solution: Z580 Windows 10: Dolby is not working

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 http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Dolby Digital Plus is not working after I installed Windows 10 upgrade, I've tried several things to fix the problem with no luck, has anyone else experienced the same problem and found a fix ???

Answer:Z580 Dolby digital plus not working after Windows 10 upgrade

hi! open control panel > sound > double click on speakers, go to Dolby tab and make sure it's on. you might also want to change your mediaplayer settings to use realtek output instead of default sound output. it's working for me.

Hi there,
 
I just upgraded to Wndows 10 Home from Windows 8.1; everything went smoothly except for the fact that Dolby Home Theater v4 does not work. I had to reinstall it using the .msi file found in the Realtek Audi folders. I chose v4 over any of the other versions because I like how I can tune the equalizer to my liking and different uses. Anyways, the regular audio works and Dolby is turned on but there is no activity appearing on the equalizer and my music does not change once adjusted. Had this problem when doing an optional audio driver update in the past when I was running 8.1. I do not have the option to rollback the driver after upgrading to Windows 10. Does anyone have a solution to this issue or know what the correct Realtek driver is to make Dolby work? This is one of my favorite features of my laptop and I really want it up and running again!
 
Thank you in advance!

Answer:Z580 - Dolby Home Theater v4 not working after upgrading to Windows 10

For those of you still struggling to find the solution to get your Dolby Home Theater v4 equalizer back on Windows 10, you are in luck. Warning: I highly reccomend cresting a backup before starting this process in case anything goes wrong. There are multiple ways to do that and I usually create a restore point and a system image.Step 1: Install Dolby Home TheaterIf you know that it is installed already skip to Step 2. Look under the control panel to see if it is listed there, if it is go to Step 2, if not go to C>Drivers>Realtek Audio Driver>PCEE4>DolbyHomeTheater.msi and double click and install the software. Restart your computer!Step 2: Uninstall Realtek High Definition Audio speaker driverGo to the device manager and expand Audio inputs and outputs. Right click and hit uninstall where it says: Speakers (Realtek High Definition Audio). Hit scan for hardware changes. If it still shows the speakers listed, right click and uninstall again. Hit scan for hardware changes and it should be gone. Do not restart your computer!Step 3: Install the Realtek High Definition Audio Driver that is compatible with Dolby Home Theater v4Go to D>Drivers>Audio>Setup.exe and double click and follow the process. If it asks for a restart after uninstalling the driver go ahead and do so. Then it will install the compatible driver and ask for a restart again to finish, do it.Step 4: Install DolbyGo to this website:http://www.thewindowsplanet.com/3765/dolby-home-theater-missing-a...

On my Lenovo Edge 15 (BestBuy Exclusive model), I recently upgraded to Windows 10 and found that the Dolby Home Theater V4 software does not work. I've tried uninstalling and reinstalling the drivers and software and still cannot get the program to work. The program will open and shows the different options available, but the equalizer does not move (like it used to on Windows 8.1) and it does not make a difference in the audio output.  This all worked before my Windows 10 transition. The audio quality is very tinny and hard to hear without this software, hopefully someone has a solution. Thank you for your help!

Hi,I'm now using Ideapad Z510. After upgraded to Windows 8.1. I'd went to the Lenovo website searching for new driver update.But, after i install the "Realtek Audio Driver 6.0.1.7023", the "Dolby Home Theater V4" is not running(audio sound not playing through).And, the "Dolby Digital Plus" is running instead of "Dolby Home Theater V4".Then, when I try to reinstall the older version "Realtek Audio Driver 6.0.1.6954" from Lenovo website, the "Dolby Home Theater V4" is running again.Truly, the "Dolby Digital Plus"'s sound is crisper and louder than "Dolby Home Theater V4". But the sound of "Dolby Home Theater V4" has more bass and more function (like Graphic Equalizer, more Intelligent Equalizer etc.).Is this an update or what?What should I choose?The newer driver (for Windows 8.1) or older driver (for Dolby Home Theater V4)?  Thanks.

Going crazy here and the support so far from Lenovo has been beyond poor so I'm turning to the forums.  I have two brand new Z580 Ideapad's, the only reason we bought them was they were cheap and had bluetooth.  Well I cannot activate bluetooth in anyway on the laptops.  There is no switch, I used the FN+F5 key and all I am prompted with is the Turn Wireless on or Off, nothing about bluetooth.  I've installed, uninstalled and reinstalled the Lenovo Power Management because I saw a number of posts referring to this piece of software.  I checked BIOS and only saw the option for Wireless.  All drivers are installed and reinstalled multiple times.  I see the Aerthos BT stuff running in the background and there are no conflicts in Device Manager, even looked for hidden devices. The laptops are Windows 7 32bit Enterprise, clean installs with only windows updates and ONLY Lenovo drivers installed IE I didn't use the Windows Update drives for anything.  Any help on where to go or what to do is appreciated.  My next move is to return these and never purchase Lenovo again if I can't get this resolved by Friday as my client is not happy at all. James

Answer:Ideapad Z580 Bluetooth + Windows 7/32 Not working

hi jrhaile,
 
Welcome to the Lenovo Community.
 
That's quite a hassle you got there. From what I know, if you press Fn+F5, you will get a "Lenovo Wireless Device Settings" menu.
 Spoiler (Highlight to read)
If you get the menu but you only see the wireless, what you can try is to:
1, Remove the AC adapter and Battery then press & hold the power button for 30secs (this drains the power off the unit).
2. Reconnect both AC adapter and battery and boot into the BIOS by pressing F2, when you're in, press F9 to set BIOS to default and press F10 to save and exit BIOS.
3. Boot into Windows and try to pair a blueooth device
 
If the same problem occurs you can try to reseat the Bluetooth module by checking the PCI Express compartment on page 42 of the hardware maintenance manual.
 
 
Hope this helps.

First lets check if the drivers for the Wifi and Bluetooth is installed properly under the Windows 8 environment.  On the desktop press the windows key + c, then click on settings, then click on control panel.  Under control panel switch to large icons for view and go to system.  Under system we will have device manager available.
 
Please check if you can see the category Bluetooth, and the wireless adapter under Network adapters category.  If they are present, go to the properties of wireless adapter and check if the driver version is the latest and if the drivers are installed properly.  The latest Bluetooth driver version for Windows 8 is 12.0.0.1671/8.0.0.206 released 10/24/2012. Here is the link for the drivers.  The latest Wireless driver version for Windows 8 15.5.0.42/6.30.59.26/10.0.0.67 released 10/24/2012. Here is the link for the drivers.  
 
If the drivers are installed properly, then we have to check if we are able to turn on and off the bluetooth or the wireless adapter.  Hit Fn+F5 and see if an interface comes up that gives you radio buttons to turn off or turn on your wireless and bluetooth adapters.  If no interface comes up, you may need to install the Lenovo Energy Management program to enable the hotkeys for turning on bluetooth and the wireless. Here is the link for the Lenovo Energy Management program.

Hello, I am having problem with wifi connection on my ideapad z580, win 8, intel core i5 64 bit.Wifi disconnects frequently while other laptop and devices are still connected. So the problem is not with the net connectrion but with laptop. Please some one help me to solve this problem. 

Answer:ideapad z580 wifi not working properly with windows 8

hi yashikabajaj08,
 
Welcome to the Forums.
 
You're issue might be similar to this thread.
 
If you have gotten the problem after updating the wireless driver either from the Intel website or windows update, try to  rollback the driver from the previous version or perform a System Restore to undo the changes that were made.
 
If the above doesn't apply to you, can you provide the wireless driver of your wifi module and try to boot into Safe Mode with Networking to isolate if there's a third party security software that might be blocking your connection.
 
 
Let me know your findings,
neokenchi

My mute button light used to stay brightly lit when I wanted to mute but not anymore. It functions normally but it just won't stay brightly lit. The other button lights stay brightly lit when used, even the volume buttons stay bright for a longer period of time than the mute light. One support person said it was working as it should but I disagree. I know how it was working before and I know it's not the same. It was nice seeing a brightly lit mute button so I knew it was okay to start a video and not wake my sleeping wife right next to me but now I have to check every time I start a video. This isn't life or death but it's really annoying and I want to fix it. Thanks

Hi I'm trying to get the hands free mode working in the food app on windows 8.1 It was working at some point but I removed permissions across the board and even disabled my webcam (in a mild fit of paranoia). Anyway I've re-enabled the webcam And the camera app works perfectly fine,I opened the food app and allowed it permission to access the camera and it still won't pick up the camera in handsfree mode. All that happens is that the GUI changes but the camera doesn't switch on (judging by the light) and motion doesn't work. Oh and it says hands free mode is off. What's up? How can it enter the GUI and not be in hands free mode?

Hi guys, Hoping you can help me out. I installed Ubuntu 13.04 over Windows 8, probably a bit impulsively, but Windows 8 was beginning to irritate me (though I did like it at first). In retrospect I should have tried a dual-boot configuration. Anyway, I can't turn back time -  I now need to reinstall Windows 8 via the recovery media I had to purchase from Lenovo (4 CDs). The problem is they're not working. When I try to boot from the first cd, it loads for about a second, and I'm brought back to the boot menu. I've tried changing the boot order (DVD-drive first, HDD second) but no luck. I even tried wiping clean the HDD using the Ubunu Live-CD (with GParted), in case the problem was that the recovery media couldn't make sense of the Linux ext-4 partitioning. So even with the HDD wiped clean, the recovery disks do nothing. Could it be that they only work if they detect a currently installed version of Windows? I can't think of any other possiblities, other than the disks themselves being faulty, which I think much less likely. Appreciate any advice. Thanks!

I'm running vista x86 with version 6213 of the realtek apo driver for the built in realtek sound card on this motherboard (p5n32-sli SE deluxe)..

I had installed the klite mega codec pack at one point.. as well as version 7.3x of PowerDVD.. all was well in the realm of dolby digital (via coax) and Vista.. i could goto the sounds section of control panel and click on the dolby digital check box and do a test.. my receiver showed Dolby Digital.. I also could select spdif in PowerDVD and get dolby digital working fine there as well..

Now suddenly, i cant get it to work.. its gone from powerdvd and if i do the test tones section in control panel i get:

"windows was unable to play the test tone"

The only thought i have, is that coax/dolby digital broke after installing SP1 ? Though i'm not positve.

I'm at a loss.. i've tried removing the 6213 driver completely and reinstalling.. i've tried other versions of the driver.. i've also tried reinstalling the codec pack..

I'm not sure if this error message is related to the driver or a codec issue?

One thing i did notice.. if i switched user accounts.. logged in.. for a split second the test actually worked.. then suddenly it stopped, perhaps after loading things.. I tried killing every task in taskman that i thought could be causing an issue, but nothing fixed it..

Any thoughts?

Thanks

I just upgraded to Windows 8 this weekend, but I noticed the sound volume was lower than usual, I checked the Dolby driver to see if I turned it off, I didn't. As music is playing, the bars moved up and down in response to the sound in Windows 7, but in Windows 8, even though the driver is on, the sound doesen't not play through the Dolby driver. As the Dolby Driver makes a large difference in sound quality on my x230t's tiny speakers, I would like to re-enable it, does anyone know how?Thanks!

Answer:Dolby Driver not working

Recently also I did the upgrade to Windows 8. I had DHT v4 (the lightweight version though that came with the laptop) installed on Windows 7 before, and all was working quite fine.As I was installing DHT v4 on Windows 8, I encountered a first problem: the drivers wouldn't install. I fixed this by booting Windows 8 with disabled driver signature enforcement.The audio worked fine now, but I encountered a second problem: DHT was simply not working. When I'm playing some sound the equalizer doesn't show any activity, just like the topic starter. Disabling and enabling Dolby with the "power button" does not make any difference. The device's description says "Dolby Home Theater v4 - Realtek HD Audio".Also note that starting pcee.exe with Windows 7 compatibility isn't fixing anything.

Since a recent update to Windows (Win 10 Pro, X64) my Dolby has been acting wonky.  There are settings under the Lenovo Settings app to have Dolby automatically control sound levels depending on the media type, but this feature is not working with Windows Media Player in full screen mode.  If I launch WMP not maximized (so the title bar is showing across the top of the screen) then Dolby functions.  If I maximize the screen, Dolby switches off and if I exit from maximized Dolby will resume after a brief delay (about one second). Since I watch a lot of video on this machine, this is driving me a bit crazy.   I have tried switching all the options on and off in the Lenovo Settings app, and the Dolby app really doesn't have many settings other than on and off.  I have reinstalled both the Lenovo Settings and the entire Realtek sound driver app (which includes the Dolby features) but that doesn't seem to do anything.

hi shahryar
 
Welcome to Lenovo Community Forums!
 
 
This normally happened after upgrading the system to WIndows 8.1 that updated the driver but left the dolby Software on original Version.
 
I suggest you Open Device manager and Uninstall the Audio Driver. (make sure to place a check on delete driver software prompt to rid of the driver completely from your system).  
   
Then Open Control Panel / Uninstall a program and Uninstall all Dolby Component
          then delete the Driver Backup under C: / Driver folder.
 
Now Download the WIndows 8.1 Audio Driver and Install it
        for your Systsem, Here it is  Realtek Audio Driver for 64-bit Windows 
 
After Extraction and Installtion completely,
     this will Creata a new back up under C: Driver folder.
        Open that and find the DolbyGUI folder Open that and you'll find the Dolby Install that matches your Audio Driver
 
 
 Hope this helps
Cheers!

Among some suggestions I found included un and reinstalling it...which I sadly did without having figured out where to re install it from. Yeah. Dumb on my part. I *did* find what could be it, but it says I need PCEE to install, which I can't find (and also want to know what it is).Anyone know why Dolby isn't working and how I can fix it or get something that *does* work?

Restore to a date where you can remember that the dolby audio sound is working. 3. Use OKR to restore everything to factory default. Note you need to backup all your personal files before doing this and might need to reinstall all third party programs after the restoration.

Hi,    i just bought a laptop Lenovo T530 which came with Dolby Advanced Audio v2 with Realtek audio drivers. When i turned it on, the sound was pretty bad as there were no preset equalizer profiles, I however had the options for Games, Movies, Music but those settings were all kept to normal. I'm no audio expert, so i couldnt create new profiles and set the equalizer settings myself because even when i tried, the sound did'nt help much. So i got to know that Dolby Home Theatre v4 has lot of options and even some preset equalizer settings too. Now my question is how to upgrade from Dolby AA v3 to Dolby HT v4. I downloaded the realtelk audio drivers from lenovo support site, uninstalled my realtek audio driver and dolby AAC, deleted the Dolby folder in the registry. I then installed the downloaded Realtek audio driver for my model and again the Dolby AAC was back , I uninstalled Dolby AAC and tried to install the Dolby HT v4.msi which i found in the PCEE folder of the installation. But i get an error when running the installation that Dolby HT cannot be installed. Any idea on how to solve this?

I only can get my front 2 speakers to work with Auzentech Prelude.

Previously Auzentech worked successfully on XP with all features working correctly so there is some compatability issue with Windows 7.

I have followed the Install instructions as posted on the Auzentech website. I will copy and paste this for reference.

1.Install the Driver in the CD first.
2.Reboot PC
3.Download and unzip the R4_patch driver
4.Double-click "setup.exe."
5.Check ?Overwrite existing shared Creative audio driver files?
6.Click OK
7.Reboot your PC after completing the installation.

The error message I get when checking the Dolby Digital box is "The Creative Audio Service is not started. Please Reinstall the application".

The 5.1 test sound pattern from the Auzentech volume control does not emit any sound.

The SPDIF properties also has a sound test pattern which displays and plays only 2 channels of sound (Front left and right).

There are no error messages in the Device Manager.

Has anyone here discovered what is preventing the Dolby Digital from working?

Answer:Auzentech Prelude Dolby Digital 5.1 not working

Updating my post from yesterday:

I had an issue after I updated my driver to the Windows 7 beta driver on the Auzentech site. My computer failed to reboot. I can't remember the message I got but it was a boot disk type error. I repaired Windows 7 and I was able to reboot once again.

I have also made the observation that even though I can get "Coaxial" to display on my receiver (that was the setting which XP worked fine on for Dolby Digital) it removes the "Coaxial" and just stereo displays.

I reformatted my computer because I thought the repair that I spoke of above might of tangled up the audio settings. This did not produce better results.

Description of the issue: Dolby digital plus is no longer working as it used to.  Description of actions:I had two chrome windows open, and I was watching a show in one. I paused it to watch something in the other window, and when I went back to the show, the sound was back to the low quality heard when dolby isn't on. I pulled up dolby, and saw it was on. However, the equalizer scales weren't moving to the audio, and the sound quality was still poor. Upon further listening, there is a minute change when dolby is turned on, but it's not the incredible difference I'd been experiencing earlier.   What I've done to muddle through the issue:-Restarted the PC, hoping the switch between browser windows had confused dolby. No luck there.-Checked Windows update to see if a driver or update had gone through recently-nothing.-Looked at the the drivers. Seems there's only one speaker driver, RealTek High Definition Audio, ver. 6.0.1.7300. It dates back to July, which I'm assuming is when the laptop was packaged. Weirdly, that's also the latest update from Acer, though Acer lists it as being updated November. Muh laptop:Aspire V3-572-51TR, purchased a month ago, most non-critical Windows updates ignored, not much else done to it. Edit: Now it's working on some things but not others.

Answer:Aspire V3-572 dolby digital plus stopped working

Hi... It seems to be something with the audio driver. The dolby software is included in the factory shipped audio driver. In order t o fix this issue, you may try reinstalling the audio driver on the laptop. Here are the steps: Press and hold the Windows key and then press the C key to open Charms.Click on Search and type "Recovery".Click on 'Acer Recovery Management'.Select Reinstall Drivers or Applications.Select Content and choose the audio codec and proceed to install it. In case you are unable to install this driver, you may go to Device Manager and open "Audio, video and game controllers" and uninstall the current audio driver. Then follow the above steps to install the audio driver. It will work..

I updated to 8.1 because supposedly, it was to offer features similar to win 7. Instead, it's even worse than win 8. Now, the sound quality on my laptop is lousy because the Dolby Audio driver receives an error message and isn't working. I went to Lenovo (I have a Ideapad N Series 580) and followed these instructions from Lenovo and microsoft, which unfortunately didn't help. I'm still getting the same error message. I wish I had never heard of windows 8.1! Many have had this same problem after installing 8.1. HELP!

This instructions are from Answers.Microsoft, but didn't work.

Open Device Manager. (Right-click on the Start button and choose Device Manager).
Expand the Sound, Video and Games Controllers section.
Right Click on the Conexant Smart Audio HD item and choose Uninstall.
Still in Device Manager, click on Action>Scan for new Hardware.
The Conexant Smart Audio item will re-appear.
Right-Click on it and choose update driver.
Navigate to d:\drivers\audio.
When that's done, close Device Manager.
Open File Manager and navigate to D:\drivers\Audio\DolbyGUI and install Dolby Home Theater.

Answer:help! Dolby Audio Driver not working after 8.1 update

I would try installing it in a compatibility mode and see if that helps.

I have a recording studio, and I'm seeing reports that many audio devices will not work with 8.1. I have a Roland Octa-Capture which is a USB connected recording interface unit and fortunately Roland had an 8.1 driver update. I've also seen some registry tweaks to make devices work in 8.1.

You may have to wait for Lenovo to issue an new 8.1 version.

Hi @iiiiirahuliii,  Welcome to the HP Forums!It is a terrific place to find answers and suggestions!For you to have the best experience in the HP forum I would like to direct your attention to the HP Forums Guide Learn How to Post and More  I grasp you are having an issue with the installation of the Dolby home theater V4.  You were able to uninstall the old driver but not install the updated driver. As Dolby does not have drivers, I am assuming you are trying to update a driver from the HP website. Dolby Home Theater v4  Here is a link to the software and driver page for your notebook.   HP 15-d103tx Notebook PC Software and Drivers You can use the Check Now option to have it auto detect any applicable software and drivers for your system. Please verify that you have the Cyberlink PowerDVD and Power Media Player Software installed. I did note that you got the message you need to install PCEE first but the installation fails. Here is a link from the WindowsSevenForum that may help.  "PCEE needs to be installed" when trying to enable Dolby Home Theater.  If that does not work I would try a HP PCs - Refresh Your PC to Resolve Problems (Windows 8) When I checked the specifications for your notebook I noticed that it came with Free Dos. HP 15-d103tx Notebook PC - Product Specifications Have you done all your Windows updates? If none of the above has helped, I suggest...

the hard disk space on my y430 is supposed to be 320gb but it only shows 252gb on the c drive and 30.3 on the d drive. is there a problem with it? i understand that some space on the hard disk will be partitioned to be used for whatever it is, but isnt 50gb a little too much? also, the space on my c drive keeps decreasing. it read 205gb at first but over the past week it has slowly decreased by 1gb at a time till its now 200gb. i havent installed anything on my laptop at all and im wondering what could be causing all these. finally, the touch sensitive key for the dolby digital control doesnt work. it lights up whenever it is touched but it does not open the dolby control centre. also, when i go to d drive, drivers and start dolby, the system immediately tells me that it has stopped working. i have moved files from the d drive to the c drive before and im wondering now if i have moved files i wasnt supposed to . i have also used OKR to restore my laptop to factory settings once about 1 month back but the files i moved dont seem to be in the original drive. hope someone here can help with all these cos it really getting on my nerves, all these problems with a rather new laptop. thanks very much thanks

Answer:constantly decreasing had disk space and dolby not working

My 320 hitachi drive on my y530 was formatting around 280gbs..... so in your case, teh number is the same 250 +30.... 280 is what these drives end-up being... the size is decreaseing becuase the computer is saving automatic restore points. there is a way to control that (i am not sure how), but i disable system restore completely as i don't need it....... as for the dolby thing. remove all teh realtek drivers and dolby software (through add/ remvove programs). go to lenovo support and download the latest drivers (you might want to download the drivers for the y550/450 since these are the newest). install the new drivers and hopefully this dolby issue will be resolved.... good luck Message Edited by latief on 05-07-2009 10:59 AM

I recently received the new Alienware 18 with Windows 8.1. Not liking that OS I installed Windows 7 Professional. I downloaded all the appropriate drivers from Dell's website for my specific computer. For sound I was given Realtek HD audio with Dolby Home Theater v4. I like the program well enough, but I'm having some issues. As the title says, Dolby only works for 1 program at a time. Say I'm listening to iTunes, Dolby will work with it, but if I open up Teamspeak, it continues to work for iTunes but not Teamspeak. If I was to pause iTunes and my friend started talking in Teamspeak, Dolby will switch to Teamspeak and everything else (iTunes, games, YouTube) will go on using default audio. With my Alienware m18x I had previous to this, I had IDT Audio. I miss that software, it would work with everything at the same time.

Things I've tried:
1. Going into sound options/speaker properties/advanced/ and disabling "Allow applications to take exclusive control of this device."
2. Updated LAN driver (someone in another forum said it fixed it for them)
3. I have a Realtek driver downloaded from their website, I haven't installed it yet because after reading their disclaimer, I am under the impression that Dolby is not included.

So if y'all have any ideas, please let me know. Thank you.

Answer:Dolby Home Theater V4 only working with one program at a time

Sounds like the way it should work? Dell has a special forum section, on their forum, just for Alienware users. May want to post there.

Dolby Home Theater and Windows 10 Hi other Acer PC users, like others, I upgraded to Windows 10 from 7 and found that Dolby Home Theater wasn't working.I found the answer to the problem was simple but not advised anwhere.I simply brought up the install/uninstall programs, then right-clicked on Dolby Home Theatre and then clicked on the 'Repair' option. Windows just updated Windows 10 again today and notified me that Dolby HT not recognised, so I did the same again and Dolby HT is now working once more. Hope this is of help.I would think that this repair should work on all PCs.     Thomas.
