Is anyone having trouble with Sound issues after upgrading to 9879? It works fine but as soon as you launch some applications, particularly games, there won't be any sound at all. Some of my games run very very slow as well.

Did you try to shut the device down completely and then restart?

I had the same issues with the sound and had to shut it down and restart it again.

I have sound issues with the win10 build 9879 too and restart don't help. System sounds and sounds from flash player are played but from all others like vlc player not and in teamspeak the microphone works but i cant hear the others.

Are there any other symptoms when this problem occurs? For example:

- Audio troubleshooter starts
- Volume control at the bottom of the screen crashes or gets a red "X"
- In Task Manager AudioSrv, AudioDG or SndVol is growing in size or crashed

Thanks!
