Apr 28, 2018  As a new version of Dolby Digital Plus seems not available for download for the latest Windows 10 audio driver (7.6.4.9), I tried to patch the file ddpc.dll in order to skip the compatibility test between the Dolby application and the audio driver. Sometimes, especially after you upgrade Windows 7 or Windows 8 to Windows 10, you find the home theater v4 don’t have sound.Of course, it may also be the Dolby Advanced Audio v2 or Dolby Digital Plus Advanced audio. Seeing as though the Dolby applications that aren’t working after the Windows 10 upgrade worked fine before the upgrade, you can be certain that the older version of the drivers for the affected computer’s dedicated audio device was compatible with the Dolby Digital Plus audio drivers.

Most of Lenovo desktops and laptops come with Dolby audio decoder and Dolby Home Theater software is the interface that you have been using to control the profiles and sound enhancements.

If you have recently upgraded from Windows 8.1 to Windows 10, there is a high chance that the Dolby Home Theater is missing and you won’t even see the Dolby icon on Taskbar. This happened to my Lenovo IdeaPad U530 laptop, and the following steps solved the problem.

IMPORTANT:

1. Note that this fix is only to be applied on Lenovo computers which was once running Dolby Home Theater on Windows 8.1 and the program went missing or isn’t doing anything after Windows 10 upgrade.
2. In the process we are going to uninstall audio drivers and install it, so it is a good idea to create a System Restore point before proceeding with the following steps. Incase if something goes wrong you can revert to your earlier system state.

First thing to do is to check if your computer has some hints of corrupted Dolby Home Theater program leftover or not. So click on Action Center and then click All Settings.

All Settings

Click System > Notifications & actions and then click on Select which icons appear on the taskbar.

Scroll through the list and look for some process that has comments Dolby Home Theater (ON). The icon may be messed up and you may be seeing a USB peripheral icon in place of Dolby icon! Take a look at below image, some other icons are messed up too like for Bluetooth it shows VLC Player icon! This is a messed up settings after Windows 10 upgrade.

Since this article focus is on fixing the Dolby Home Theater, let me show you how to fix it.

Fix Audio Drivers after Windows 10 installation

Before heading to fix Dolby Home Theater, it is recommended to first fix the audio drivers, though audio is just working fine on your computer. The problem is Windows may be installing some other audio driver while upgrade that is not compatible with Dolby.

1) Type Device Manager in the taskbar search and hit enter.

2) Expand Audio inputs and outputs and right-click on Speakers .(something). In my case it as Speakers (RealTek High Definition Audio).

Uninstall Audio Driver

3) Go to C:Drivers > Audio and run the setup.exe file. Don’t worry about the location of Drivers folder in the image below, I moved that folder to D: drive.

4) You need to restart your PC during the process.

5) Once complete, you will see the Speakers (RealTek High Definition Audio) back in device manager, but this time it is the drivers that is compatible with your Lenovo PC.

Install Dolby Home Theater

1) Download Dolby Home Theater program for Lenovo PCs:

2) Run the file that you downloaded gaas05ww.exe.

3) If your Lenovo PC had Dolby Home Theater earlier, you will see the program shows Repair and Remove options. Click on Repair and proceed to Finish it.

4) Now to check if it solved the problem, go again to the Notifications & actions and look for Dolby… Looks at the corrected icon in my Lenovo laptop, it says Dolby Profile Selector (Dolby Home Theater (ON), and this is how it should be.

5) You will also see the Dolby icon back on taskbar!
