V5-552P Windows 10 audio driver got rid of Dolby Home Theater

A few days ago I upgraded my laptop to Windows 10 and everything worked fine, including Dolby Home Theater. However, today I decided to install the Windows 10 audio drivers for my laptop on Acer's website just to make sure they were fully updated, but now Dolby Home Theater is completely gone from my system. Why does the Windows 10 audio driver get rid of Dolby Home Theater and how can I get it back?

try to install this drivers:http://station-drivers.com/index.php/downloads/func-startdown/1591/ 100% trustable websitedouble click on exe, on the extracted folder look for setup.exe file and run it.

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) @@

Hi all
Could you try out DAA or DHTLightweight from my link and just install the Dolby software without overriding your Realtek Driver? I am not sure whether would it work, but worth a try. I have tried on Y460, W520 and G560 with great experience.
If the older Dolby software does not work with your existing Realtek driver, you could install the DAA or DHTLightweight with their driver to overwrite and see how it goes.
Thank You

Dolby Home Theater v4 not working after upgrading to Windows 10

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! JakeStiebs My unit: Lenovo Ideapad Z580 running Windows 10 Home with Realtek Audio Driver 6.0.1.7535

one more thing. I was not able to download cleanup tool/online scanner too. but may be it has something to do with my internet bandwidth. and other strange thing i observed is that before restart i was not even able to turn off all security features. but after restart that problem seems to be corrected.

Can't install Dolby Home Theater after upgrading to windows 10

HI, I have an Acer v3 572g. I upgraded from win 8.1 to win 10. Everything is working fine except that the upgrading process completely removed the Dolby Home Theatre application and its drivers and automatically installed the Realtek high definition drivers, after I found out about it, I tried some tips I found online , this is what I did: Downloaded the audio drivers from the Acer website, uninstalled the default audio drivers then, I installed the acer drivers followed the installation process restarted my computer after that, I try to run the DolbyHomeTheater installer found in the PCEE4 folder but after I open the setup file it says: DHT cannot be installed. it doesn't explain why it cannot be installed whatsoever. I can't get this app installed no matter what I do, I've tried different things like installing and uninstalling multiple times, running the setup in compability mode... I don't know what to do now Any help will be very appreciated.

Hi! Thanks for your reply, I did exactly what you suggested but it didn't work for me. I'm able to install the audio drivers but when I try to run the Dolby Home Theater setup, it gives the same error "DHT cannot be installed" I now tried running the setup in troubleshoot compability mode it says: "Settings applied: Windows compability mode: Skip version check.Then, I click on test program but get the "DHT cannot be installed" error.After that, Windows compabilty troubleshoot asks me whether the problem is fixed or not, I click "no" then it says: "issues found: Incompatible program: DolbyHomeTheater is incompatible." But the odd thing is I'm able to install Dolby Advanced Audio v2 and not DHT v4,
I don't know if this is an issue with Windows 10 and Dolby, Acer or both are working on it or something went wrong during the upgrading process...

Cannot launch Dolby Home Theater after Windows 10 upgrade

Hi, I'm using a Z50-70 and one of my favorite things about it is the Dolby Digital Plus feature. But after upgrading to Windows 10, I cannot launch it anymore. All I have is this sucky Conexant audio driver. Will there be a solution for this in the future? Because I'm thinking of going back to Windows 8.1 even if it is tad slow just to be able to use the Dolby audio again.

:0hey i found the solution uninstall the dolby driver if it was installed previously now download the latest (http://support.lenovo.com/hr/hr/products/laptops-and-netbooks/lenovo-z-series-laptops/lenovo-z50-70?TabName=Downloads) and restart ur pc the go to c drive path:C:\Program Files\CONEXANT\Install\Audio\DolbyGUI install it from there it works for me...........

Hi mido112k,
I understand that you are having a problem installing the Dolby Home theater on your HP Pavilion G6-2321ee Notebook PC. I will try my best to help you with this.
I suggest that you restore the original Performing an HP System Recovery (Windows 7) and then install the update driver.

G780 - Windows 8.1 update - Can't Start Dolby Audio Driver

I just updated my G780 to Windows 8.1 this morning. every time I boot up the computer, I get an Error message stating" Dolby Advanced Audio - Unable to start the Dolby Audio driver. Please restart the computer or reinstall the driver if the problem persists. I have restrtaed the computer and I do not know where the driver is for this or where to install it. Please help. Computer is just over a month old.

hi
The Driver I gave you is very huge (185MB)
      This is because it contains the dolby installer,
         It depends on the Version where it will be located after installing the audio driver
and what name it will have,
Try Searching then for Dolby but make sure you open you drive C: and do the search
or otherwise
      Try Navigating these folders
                 Open My Computer or ThisPC open you Drive C:
Now we'll look for the dolby Advanced audio installer
      Look for these folders as these are through my experience where it goes
                  Also when you find the right folder you will find two of them together (Dolby Advanced Audio and Dolby Home Theater) just install what came with your system the dolby advanced audio.
             C: Drivers / Conexant (Then look inside on all the folders inside it lkook for anything says like dolby)
             C: Conexant (Then look inside on all the folders inside it lkook for anything says like dolby)
             C: Program files x86 / Conexant (Then look inside on all the folders inside it lkook for anything says like dolby)
             C: Program files x86 / Conexant (Then look inside on all the folders inside it lkook for anything says like dolby)
Trust me its in your PC now you just need to look for the installer

(Win 8.1) x230 Speaker volume strenght / Realtek Audio Driver may be unnecesary

Hi
This is more a poll/discussion rather than a question. I wanted to share with you that I have a x230 and as soon as I installed Win8.1 x64 audio worked fine with "Intel High Def Audio" driver. I though sound was kinda weak (I know this is a tiny laptop but it was a lil' TOO weak). Went to Control Panel>Sound>Speakers>Settings>Properties>Enhancements and activated "Loudness equalization" and noticed there WAS like 50% increase for windows sounds, 0-5% for WMP and around 20% for youtube vids. Then decided to install Realtek HD Audio x64 but since it had to reboot and all that and I dont have any "decibelimeter" or whatever, I couldnt take note of scientific results but I THINK the Realtek MIGHT have increased volume another 20% OVERALL but also noticed the driver is 222MB!!! which was hard for me to believe, still dont understand why so heavy, plus, you get a background process from the Realtek thing. What do u guys think about this? How do you use you "ultraportables" in matters of sound/speaker strenght? Would you install the driver?
PD: Keep in mind "Loudness Equalization" enhancement disappears after installing RT driver.
Thanks for any comments.

Several tweaks with audio settings on my x220 with win7 couldn't increase the audio volume and improve the "quality" , if we can say so about that one via the cheapest internal chip. I've deleted Conexant drivers and sw and installed Dolby Home Theater v.4 with x220 preset. The difference is very big.
The main thread is here:
http://forums.lenovo.com/t5/General-Discussion/Dolby-Home-Theater-v4-for-most-Lenovo-Laptops/m-p/620...
Also there are many threads aboard regarding DHT and win8 with different links to the sw here.
I know only DHT supports win8 and Realtek too.

U530 Touch - Audio DRIVER ERROR - This device cannot start (Code 10) - Windows 7

U530 - High definition audio device - ERROR - This device cannot start (Code 10) Windows 7, please see the picture
Picture link (hosted on photobucket.com)
I got all drivers up to date including the BIOS, everything is working fine (the sound works, microphone works...) but this error is kind of annoying to my eyes so if anyone know how to fix it please help.
I tried to uninstall this and let windows update install it again => not worked, same problem.
I tried to re-install the Realtek driver (uninstall - restart machine - install - restart machine) => same problem
And another probelm which has not been solved yet is the Bluetooth icon keep blinking on battery mode (windows 7), you can see more in this thread

What kind of reinmstall did you perform? If you used the recovery media, then this will be pretty simple. Boot to the recovewry media again and this time select the Reinstall drivers and applications option. Find the audio driver on the list of available drivers, put a tick in the box to its left and then click on the install button in the lower right hand corner of the window. The driver will be installed. Your list will be different than the following one, but this is only an example.
