Whats up guys.

Here's the deal. Recently whenever I start iTunes a message pops up saying, "iTunes has detected a problem with your audio configuration. Audio/Video playback may not operate properly." and there's no audio playback at all.

I've tried re-installing quicktime and itunes, but that didn't work. Device manager says the ATI T200 Unified AVStream Driver cannot start so I thought that might be part of the problem. I'm trying to get this fixed asap and I'm running out of ideas on what to do. Anyone know whats up?

Thanks
