I decided to make a new post about this, since I know I'm not the only one on this forum with M-Audio sound cards. When I updated W7 to a new build (7048 and newer), I found that I was having compatibility issues. I could get the audio to work perfect, but the computer would hang on the shutdown screen. It actually took me quite a while to isolate the issue, since I did not know at the time what may be causing it. As it turns out, this issue is well documented on the M-Audio forums, and there is a workaround to solve the issue until m-audio actually releases a proper driver. (knowing them, it may be years before that happens.) Note: I couldn't get the link to work, so I made the file myself following the directions. It is actually faster to just make your own than it is to hunt for the one he made.
