Dolby Digital Plus audio driver is 7.6.4.9 and software expects version 7.5.1.1

I have a Realtek ALC3661 and are running Windows 10 Pro.

Recently I installed the Windows 10 Anniversary Update on my Alienware 18 and, since then, I've had nothing but
problems with the sound panel.  The biggest errors are that system sounds won't play when you've set them, and my Corsair Void Wireless has a setting for 8-channel sound, but is permanently inaccessible, even after uninstalling it and performing a clean reinstall.

Now, from what I've read, Dolby has a huge issue where it's incapable of updating itself when any audio driver is newer than the software it is compatible with.  Problem is the factory driver for my sound card is 7.5.2.5, and I can't seem to find a new version of Dolby Digital Plus online I can simply install, to replace the existing one.

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.

And it seems to work perfectly ! (with audio driver 7.6.4.9 and application 7.5.1.1)

Finally I was able to access the Dolby configuration screen again :)

So here is the ddpc.dll file to install (as a replacement for the original) in the application folder (C:\Program Files\Dolby Digital Plus) :

(if you don't trust me, compare this file and the original 7.5.1.1 version, you'll see than only 3 bytes were modified)

Last night we had the issue with the Realtek drivers not having Dolby Digital or DTS in the drop down list.

Our work around:  VLC Media Player 64-bit 2.2.8

https://get.videolan.org/vlc/2.2.8/win64/vlc-2.2.8-win64.exe

In VLC, Audio Menu>Audio Device>Select Device

And Tools Menu>Preferences>Audio>Dolby Surround>Set to On

Good luck!

thanks WizouFR!!

Your fix worked perfectly.

Now Microsoft, surely this needs to be fixed- it's 2018 and we're relying on patching Windows DLL's ourselves?

au revoir mon ami :-)
