I will be watching a movie or playing counter strike and my sound will randomly stop working. I open up my mixer and they are all at max volume, my device manager says I have up to date drivers. It seems to go along with a notification, but not always. And my event viewer doesnt mention anything. As soon as I close out and open it back up its working again..
* I get a lot of random notification sounds as well. Like the hardware remove/insert sounds. Not sure why.
