Audio Problem

My audio hasn't worked ever since I uninstalled Windows XP, and installed Windows XP Professional instead. I have audio drivers installed, and I'm almost positive they're working. When I try to go to Volume Control and raise the volume, it tells me there are no mixer devices available. I've already tried starting Windows Audio and all of its dependencies, but that didn't work, and they were all already started and automatic. One other thing I'd like to note is that iTunes detected a problem with my audio configuration (and a few other programs, but I forget their names), and didn't even play any music. This report from Everest will probably say more about my problem then I can, I'm not sure how much of the massive report I should post, so I'll just post the top and the Summary.
