So I was testing some MIDIs on this card and all of a sudden the playback just hanged. All mixer settings were completely messed up. I rebooted and loaded my defaults in ProMix. Couldn't get any sound out of it at all in Windows. Well, I did a quick initializing in DOS and everything worked, so I just reinstalled the drivers and it's all back to normal again. In fact I'm pretty sure I've had the same thing a few months ago but didn't think too much about it. Is it a known bug or just general VxD driver fail?
