Hi, I have been struggling all day with no sound on my PC after upgrading to Windows 10. Any help would be greatly appreciated. Thanks!
Answers (N/A if not applicable)
Provide a detailed description of the issue
I just upgraded to Windows 10 from Windows 7. After the upgrade I am no longer getting any sound. Furthermore, the Intel Display Audio sound configuration only has an option for 2 channels. The option for 7.1 is no longer there (it was there in Windows 7). Under encoded formats it no longer shows support for Dolby Digital, DTS, DTS-HD MA, and Dolby TrueHD. (These were all listed under Windows 7)
Please place an X to the right of the option showing how often you see this issue using specific steps. (Ex: 'Every few times a game is started it flickers.' <- This would be "Often")

How to repro
Please provide steps to replicate the issue. These steps are very crucial to finding the root cause and fix.
- I have updated the Intel Graphics drivers to the latest according to the Intel Driver Update Utility.
- All of this worked perfectly fine in Windows 7. I only had problems after I upgraded to Windows 10.
- Currently I have no audio at all except for system sounds. Video is silent. This is my home theatre PC so I'd like to get it working to be able to watch movies again.
