Skipping and Popping Sound

[QuickStop]

for some strange reason, since yesterday afternoon, all sounds that play on my pc speed up, slow down, pop, and skip. but the weird thing is, is that it doesnt happen when i turn the computer on, it takes a while before it starts fuck up.

the sound was doing this on a few programs a few months ago, but it was because total recorder was taking over the sound mixing. i checked everything, and all the sound output is controlled by my soundblaster live card.

this whole thing is really annoying.
