Got the very same issue last week with an asrock mobo ,a days fiddling got nowhere so i did a reinstall of windows which cured it.
Windows is now fully updated so i guess a bad update caused it ?
I tried all the windows fixes ,refresh etc so in the end did a complete reinstall from disk ,luckily i had done a complete back up of steam (games thing) or i would be downloading 200gb of games for the next two months!
The interesting thing was suddenly the sound came alive for ten minutes then went so i guessed it was a windows issue rather than a hardware problem

Believe NOTHING anyones says or writes unless you witness it yourself and even then your eyes can deceive you
There is only one opinion i listen to ,its mine and its ALWAYS right even when its wrong
Its far easier to curse the darkness than light one candle
