Constant 'static' noise when playing games?

[bcda12]

Ive been using Dolphin for a while now, but i can't seem to figure out why the emulator (after a while) when playing Resi 4 or SSBB etc, the audio will start to spew loud static sounds and will go away after a long time....but then come back again after a long time :|

I can't seem to get it to stop working
