Right. I need a driver for the CM6501. There is no windows 7 version available. Drivers for any other OS aren't working, that's when I get the error. Are you saying I can d/l any of the drivers as long as it's C-Media? Weird thing is, this just started last night while watching a movie. I hadn't made any changes. I'm wondering if my onboard sound is just fried and maybe I should buy a sound card. The MoBo is pretty dated.
