[alsa-devel] Popping noise on HP dv6000z (CX20549) running x86 kernel

Here's my situation:

If I play a game (any game, in particular, however, neverball/putt or sauerbraten), the sound has these little soft "pop" noises happening so quick per second I cannot count them. This is when I'm running on an x86 kernel, however, when I run an x86_64 kernel, these are not present. I've got a 64-bit processor, specifically an AMD Sempron 3500+

Does Anyone know why?

I've got a conexant CX20549 in my laptop.

Thanks, enigma
