just want to report that this happens to me as well. seems to happen after my system has been on for a long time w/o a restart. I'm thinking of just having an auto-restart script once per night so to prevent this.
What is the easiest way to automate a myserver restart?
I do a restart every few days via Windows task scheduler, but in my case it doesn't seem to help. I've had instances where this audio bug occurs immediately after a restart, and other instances where it takes days to occur again.
Which audio device/chipset are you using? I'd be curious to know if this issue is specific to a certain line of audio chipsets.
