audio

The title menu music will work but once in the game the sound cuts out completely. If I stand still for long enough it comes back sometimes, but quits again if I move. I need help!

I was just doing a Mines run with my nub HUcaseal, having a good time killin' robots when all of a sudden the game's audio just... Stops. No BGM, no sound effects, no nothing. All other audio on my PC was working fine, so I know it's just PSOBB. I checked my volume mixer and PSOBB wasn't muted...
