Dolby Home Theater V4 changed to Dolby Digital Plus after Realtek Audio Driver update Windows 8.1

Question: Dolby Home Theater V4 changed to Dolby Digital Plus after Realtek Audio Driver update Windows 8.1

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. (confused now) @@

Answer: Dolby Home Theater V4 changed to Dolby Digital Plus after Realtek Audio Driver update Windows 8.1

I only installed audio driver ver. 6.0.1.6798 which includes Dolby Home Theater V4. Since no issues are encountered I have not updated to the latest version for my unit (ver. 6.0.1.7027). Does this Dolby Digital Plus mentioned by you better than V4 in some aspect aside from the ones that you already stated?

G'day From Australia I'm basically trying to help people with Dolby Home Theater 4 if they have Realtek Audio Software installed.

Okay so if you're getting an error message saying the driver is wrong when you install Dolby - you'll have to go to Control Panel then Programs then uninstall programs and uninstall Dolby.

Once it's uninstalled use you're file browser (the yellow folder near the start Button) and click on C drive. Click on Programs and Find the "Realtek" folder. Click on "Realtek" then click on "Audio" click on the file "PCEE4" then click on "Dolby Home Theater" this will install the right version for Windows 7 - simply follow the promps, and you good to go - remembering you need to click on the short cut of Dolby on your desktop and click the on button to activate Dolby.

Hi Guys,
 
I recently upgraded a W520 to Windows 10 with the Dolby HT installed. Of course it no longer works and the audio is horrible again, especially from the internal microphones.
 
Has anyone come up with a way to install the Dolby Digital Plus on the Conexant based systems? I really need the improved audio for my softphone ASAP.
 
Thanks.

Hey guys! I'm new here as a user, but I've been here several times before.


Alright, I have some questions and maybe some (problems) if possible, would be very glad to solve.
So here goes...

Okay, so I purchased this Acer Aspire V3-571G Laptop not too long ago. The laptop works great.

But there are some things. First of, the laptop came with Dolby Home Theater V4, it's great, I like it. But I
also noticed that there is the Realtek HD Audio Manager. But when I open it up, the tabs like Sound
Effect, Room Correction are missing. And in the Speaker tab the stereo option is greyed out. I know this is because that I'm using the original drivers from Acer and (maybe) the options are used by Dolby Home Theater, right? But the thing is, that I'd like to have the tabs in Realtek HD Audio Manager.
Another thing is, beside the laptop's speakers, it's written ''Dolby Home Theater V4'', and far to the right, it's written Professionally Tuned. This is normal, they put in Dolby Home Theater inside the hardware, right? But do I also have Realtek inside it?
But anyways the drivers im using are the original ones. And btw, if I use older drivers like R2.41, they install succesfully and all, and I have the Sound Effect Tab, though not Room Correction. I also have a another option in the Speakers Tab called Headphone Virtualization or something like that. But the weird problem is that with the older drivers, in Realtek HD Manager it says, Analog and beneath that, it says ''Mic in''. And ... Read more

Answer:Realtek HD Audio Manager and Dolby Home Theater V4

The Dolby home theatre is a software enhancement to the RealTek. Many times in systems with software enhancements (there are several such as SoundBlaster MB, Beats Audio, etc) those programs provide any audio "enhancements".

RealTek drivers are customised by the PC vendor for their application. Generic sound chip drivers (e.g. RealTek) or RealTek drivers from another vendor may or may not work (install) and may or may not work properly after installation.

This is the notice that is posted on the RealTek site about their drivers:






Quote:
Audio drivers available for download from the Realtek website are general drivers for our audio ICs, and may not offer the customizations made by your system/motherboard manufacturer. To be sure you obtain the full features/customizations provided in your original audio product, please download the latest drivers from your system/motherboard manufacturer's website


If you want a PC with all the RealTek bells and whistles I suggest you return this PC and buy one that has what you want.

Hello, when I reboot my Y50-70 Windows 10 laptop and log back into it, Dolby Digital Plus Home Theater is shut off. I then have to reenable it by accessing Dolby Digital Plus Home Theater either through Device Manager or All Apps.
 
Is there or will there be a fix for this issue? Its a PITA to have to manually reenable it each time I reboot my laptop.

As you can read in the title, my Dolby Digital Home Theater works as software (means I don't get an error message) but I can't hear an effect like normally. I'm using an Ideapad Z500 Touch runnning Windows 8.1. I resetted my computer last week and updated everything. Without doing anything Dolby doesn't work anymore. I tried insalling all drivers I had found but it didn't work with any. Help would be great! Pinolpier

Answer:Dolby Digital Home Theater 4 shows no effect

Check in device manager to see if under Sound, Video and Game controllers your audio is listed as High Definition Audio Device, instead of Realtek High Definition Audio Device. If so Windows update has replaced the driver with Microsofts generic driver. One Key Theater and Dolby need the Realtek driver. You can roll back or reinstall the current Realtek driver. However I use my laptop for professional editing and the Microsoft driver is better, with higher performance. I get stuttering on audioscrub with the Realtek driver. The loss of One Key Theater and Dolby EQ for me is of little importance as I consider them only marginally less than bloatware. I have been involved with Dolby products both professionally and as a consumer for many years and I find their noise reduction and matrix solutions of dubious merit, plus their aggressive pro licencing is incredible. You can find just as much EQ control in Windows Media Player for example or other software, should you need it. The JBL equipped laptops have good sound anyway and the Microsoft driver has more pro control anyway than the stark Realtek one. I realise that you may notwithstanding still want the Dolby and OKT, so the first para is the solution. Hope this helps

Hello All, I cannot seem to get the Dolby Home Theater v4 software to work correctly. I understand that the software is bundled with the Conexant HD audio driver and I downloaded 0zau06ww.exe. When I play audio I should see the spectral analyzer respond to any audio stream, but it doesn't do that anymore. Turning Dolby on or off has no effect on the sound playing.  I've made sure nothing is preventing Dolby from running by going into Sound and making sure that the Enhancements box is unchecked. Did a clean install as suggested, still nothing. The GUI comes up, the faders slide up and down on the equalizer, but there is no change in sound. What gives? Smart Audio also came bundled with the driver, I know there's a Windows 8 version that includes this.  Not sure why Lenovo either doesn't show the older software anymore, or at least have a link to archived files.

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?

Answer:Dolby Home Theater v4 for Windows 8?

Download and install both Conexant and Dolby packages from the same page. If possible, with similar release dates.That should do the trick.But being a 420s owner... May I ask why do you want it? The conexant driver it's much worse than the Windows default. And Dolby doesn't work so great. You can achieve better sound using software Dolby filters. Good luck.

Does anyone know how to fix the problem with DHT on Lenovo Thinkpad S430? I haven't found a solution on the internet. When will Lenovo release a new driver? Thank you

Answer:Windows 10 Dolby Home Theater V4 on S430

Dear Jinsan,
 
Welcome in lenovo community,
 
DHT is related to the Audio driver, so you can right click the audio driver from the device manager and choose update driver software.
 
Also you can try to install the driver from Realtek website.
 
Regards,
Joseph

I've just upgraded my T430s to Windows 10 and Dolby home Theater v4 no longer runs. The only solution I can find leads me to this page: https://support.lenovo.com/us/en/documents/ht103618 This page tells me that a different dolby software will be available via my computer's driver profile page - it is not. Called tech support, they told me to go to Dolby. Went to the Dolby website, and they pointed me to my computer's drive profile page (the support page). What gives? I really enjoyed the audio quality it provided. I'd love any solutions or help you could provide. Will continue scouring the forums. Edit: Found the solution here: https://forums.lenovo.com/t5/ThinkPad-T400-T500-and-newer-T/Dolby-Advanced-Audio-problems-with-T430-...

Hi,I have the same problem. Today I went for Windows 10 and then realized that the Dolby is not working - could not find it anywhere.According to the advice I found on Lenovo websites I unistalled the Conexant drivers - just to find out that for my product - ThinkPad Edge E420s there is no support for these audio drivers for Win 10. What do I do now? Should I try to install again the ones for Win 7? Or the ones that were released for some ether Edge types?I am such a dumbo. Anyone can please help me? Thank you.

Answer:Drivers Dolby Home Theater v4 for windows 7

hi Jalari,
 
Welcome to the Forums.
 
For  Dolby Home Theater v4 to work, it must match the required version by the Realtek Audio Driver. If this was working before, try one of the following:
 
1. Rollback the driver
  - open Device Manager, navigate to Sound, video, and game controllers
  - right click on Realtek HD Audio > choose Properties. On the "Driver" tab, hit Rollback Driver then reboot.
 
2. Re-install both Realtek HD Audio and Dolby Home Theater
  - open Control Panel (large icon view) > Programs and uninstall Realtek HD Audio and Dolby
  - open Device Manager, navigate to Sound, video, and game controllers
  - right click on Realtek HD Audio and choose uninstall (check the box that says "delete driver software") then reboot.
  - download and install  Realtek Audio Driver v6.0.1.6559, reboot the PC and test
  - if the Dolby Home Theater v4 interface is missing, navigate to C:\Drivers folder.
 -  on the drivers folder, navigate to the Realtek HD Audio then Dolby GUI folder and Install the Dolby Advanced Audio.

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!

I had upgraded my Y500 from Windows 8.1 to 10. Before, I had One Key Theater installed and it worked perfectly fine. I didn't have the Dobly Home Theater app. The Windows 10 Creator's Update came to my laptop and I upgraded last week Wednesday. On Friday, my laptop wouldn't boot up, not sure if this is related to the Creators update. I couldn't perform Start-up Repair, System Recovery nor a PC Refresh. I ended up having to reinstall Windows 10 from a recovery drive I created a while back. My laptop is now recovered except for the tedious part of reinstalling all my apps. I've been trying to reinstall One Key Theater and I keep getting an error message saying that this application does not work for this version of Windows. Furthermore, I noticed the Dolby Home Theater application but it does not work. The icon appears in the notification area of the task bar but whenever I try to open the application fully, it crashes.I've seen posts about these very same problem for Dolby Home Theater and they all recommend uninstalling and reinstalling the audio driver and also reinstalling Dolby Home Theater which I've done a couple times now but this still does not work.Will Lenovo be releasing a version of One Key Theater that works for Windows 10 Creators Update?Will a fix come out for this problem with Dolby Home Theater?Has anyone found a solution?

First make sure that the Audio driver and the dolby will be in sync.
Open Device Manager 
    Uninstall the Audio Device Under Sound and gaming controllers / Make sure to place a check in the Delete driver software prompt.
           
Now make sure you don't have any dolby components
    Proceed to Control Panel / Programs / Uninstall a Program
                     Uninstall all Dolby Related programs
                             Restart if Prompted
Now install this software driver
 
https://download.lenovo.com/consumer/mobiles/audio143w81.exe
When you install this software it will show you a directory path whre it will extract, Make sure to Remember the path
 
This next xtep is important

Open the directory path where the Audio driver installer extracted the Audio driver.

Check all the folders inside it and find the Dolby Installers, Install the Dolby either Advanced audio or Digital plus.
 
ANd you should now get your dolby back
 
Hope this helps
Cheers!

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...

The current driver version is 7.6.4.9 but the software application expects version 7.3.2.2. It asks me to install a valid driver and software application combination. So far as I am aware I have downloaded and installed the latest drivers from Lenovo. Help

I recently installed Windows 7 on my Y510, everything works fine except the Dolby Home Theater sound doesn't work.  I have sound out of the computer speakers (the two side ones), but nothing out of the sub-woofer underneath.  I also have sound through the headphone jack, but not like I did before.  I have worked through all the options available in the control panel, but nothing helps.  Andy suggestions.

Answer:Y510 Dolby Home Theater Sound no longer works after installing Windows 7

This is so frusterating, I have bought Lenovo P580 laptop and the  new Windows 8 came out so I updated it to this Windows and I didnt like it so I had to downgrade to Windows 7 and of course all my programs were deleted including my pre installed softwares. My new audio is not that good compared to what it was before and I think it has to do with Dolby Home theater. I  updated my drivers BUT i couldnt find any drivers specifically for that. PLEASE HELP ! I dont know what to do 

Answer:Dolby Home Theater v4

It's not a driver. It's just audio-enhancing software, and Lenovo seems to have forgotten to put it on the P580's downloads list. But here you go: http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS029566

Answer:Dolby Home Theater v4

I've wondered the same thing. It seems the v2 software can take a long time to open, when you want to switch profiles, and the X1 Carbon ships with the v4 software.

I have problem with OneKey Theater. As far as I know it contains dolby home theater v3. When I change OneKey Theater mode from normal to movie left channel is playing louder(speakers or headphones). I can't find any settings for Dolby home theater or OneKey Theater to adjust it. When I change voice levels in Realtek HD Audio driver or windows after I made it balanced right channel has more bass(is muffled) and left has more sopranos. That doesn't solve my problem Intelligence mode also doesn't help - same problem with sound. Only normal mode works fine.any ideas? how can I fix it?? ps. I have just reinstalled both drivers still same problem.edit. I have Y560

Answer:Dolby Home Theater v3 problem

hey erisen,curious, after uninstalling both drivers.. have you check the sound quality of the Y560 when windows installed its generic sound drivers ?was the right channel muffled ? was the left channel still louder?

Answer:Dolby Home Theater v4 not functioning

Rocriz,
 
what do you mean by upgraded?  You need to inform members which operating system you had installed and which is now installed.
 
If you happen to have upgraded from 8 to 8.1 you'll find quite a few threads about this by using the search function.

Why isn't the Theature package supported on the T520's and such even though the audio driver is the same for it. The Dobly Theater won't install. PCEE needed it says.I tried it for the heck of it just to see since my sound it pretty bad quality for everything expect beeps and alerts. Its the worst audio in any notebook I've seen and owned and worked on. That is alot of notebooks and dozens of brands as well.

Answer:Why isn't Dolby Home Theater available for the T520

Maybe it's not supported because T420 has Conexant CX20672 codec chip and T530 has Realtek ALC3202?..

Hi,Have a DVD-R drive installed with no analog or digital audio cable. The sound from CDs or DVDs somehow comes through anyway through the ribbon cable, running XP.Have an Audigy 2 sound card hooked to my home theater receiver using a mono 1/8" plug to RCA plug cable between the digital out on the sound card and digital in on the receiver.Getting excellent stereo sound from the receiver this way. From what I've read, I should be able to get Dolby Digital on DVDs passed through the sound card to be decoded by the receiver using this hookup and PowerDVD to play DVDs. No Dolby Digital is being detected by the receiver.Think it would do the trick if I added a digital audio cable between the DVD-R drive and the sound card? I think there is a hookup for a digital cable on the back of the DVD-R drive. No hookup for a standard analog audio cable though. Anything else I might be doing wrong?Thanks MUCH for any help!!!  Roy

Answer:Dolby 5.1 to home theater receiver?

your sound card can decode the Dolby Digital sound by itself , the sound it send out is already decoded, and all you have to do is hook it up to a digital amp

Each time my computer shuts off, this program resets as well.  How do I leave the Dolby Home Theater on?  I checked the program and it provides no such settings to leave it on.  It almost looks like I have to enable it each time the laptop turns on which would be very weird. I have a P500 series from Best Buy.

Uness you turn it of It woudn't reset AFAIK.. Does the app run when you start windows? Is so you can see a minimized version running near the system clock

If Not first check if you have the program installed under Control Panel / Programs and Features.
 
Let me know your findings

How do you unistall this? I have a Y580.  The reason for wanting to unistall this is because from looking around the net, I saw that it's the cause for realtek sound effects tab not to show up and I find that far more useful than the dolby home theater.

Answer:Dolby home theater v4 uninstall?

type add and remove in the search box and then click on the result then select dolly home theater 4 , but make a restore point in case you want to get it back.
