Try disabling soundcard's hardware acceleration first, at first sight, it would be the last solution for that kind of problem, but beleive me i've had that kind of problem even i a fully-video compatible computer which the only hardware change was Creative Sound card!

I was tried a lot of codec/filter combinations, settings, disabling background processes, even uninstalling existing DirecX (what a pyscho huh :) ) But as i said, some problem may be like that...

For example, my on-board sound chip is C-Media CMI8738, of course there is a "good" difference when compared with Creative Vibra 128 (CT4810), but still i'm not "fully" comfortable with this driver and card.

I'm intended to say: Some newer drivers solves some "new" problems but some older drivers are more bug-free, that's why newer is not always the better.
