I am using a Lenovo Laptop G400s touch that came with Windows 8 preinstalled. Yesterday I updated it to Windows 10 and after that whenever I boot my pc to desktop I get an error message saying that "Unable to start the Dolby audio driver".
I tried below thread but I couldn't find audio driver for G400s. Please help me to get Windows 10 audio driver to perform the reinstallation.

Welcome to Lenovo Community Forums!
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
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

You can use the file in the Drive D: BUT
You will have to make sure that your Audio Device is running with the driver in that same server
You computer should be running the same version of the Dolby and Audio driver,
This is why Removal of both is the first step in the guide I posted above.

I have followed the steps mentioned.
After install the software from the link. I got check box to install Contexant at Finish page.
I clicked and it got installed.
After that I tried to install Dolbe software, but when I execute setup.exe from folders Dolby Config and DolbyGUI there is no reponse.
Before Windows 10 upgrade I used to have Dolby at my task bar icons, but now not available.
And I played demo content of Dobly there is no difference when Dolby Off/On. I really wonder whether Dolby system is working on my notebook or not.
Please help me to solve this issue.

Hey I have that issue too. my dolby Advance audio v2 can't work properly. there's just an update on windows update, but it's just Dolby Digital Plus not Dolby Advance audio that I want.
Dolby advance audio is better in any way. please fix this issue.
I use Lenovo G400S.
Now in my Control Panel, there's two dolby.
but Dolby Digital Plus that work, and I didn't like it.
it's sound crap.

I solved this problem uninstalling "Dolby Advanced Audio" in control panel. After it, download the installer file (http://support.lenovo.com/br/pt/downloads/ds028945) and reinstall, unchecking the 3 boxes: "Install the profile selector"; "Install the profile editor" and "Install the demo application".
