2.91, sound sometimes gets distorted

[slpz]

Sometimes when I'm using Winamp, the sound becomes corrupted. Whether I'm listening to an mp3 or watching a movie, the sound will become all warbly and distorted. I don't know exactly how to reproduce, it happens sometimes when there's a load on the cpu.
I'm running 2.91 on xp pro sp1, on an xp2400+
It's only a problem with Winamp (i.e. no other players ever have this problem)
It's making me have to use other programs to watch videos and stuff because I don't like randomly having sound get corrupted. I want good winamp back! lol. When I close Winamp and reopen the program goes away (just to come back later)
