Sound performance problems in FreeBSD

Hello list, I've experienced sound performance issues from the very first 
day I tested 5.x. The problem was that sound skipped whatever I did. Now 
I've reduced the problem a bit with changing my kernel config (No, any 
debug option isn't on or haven't ever been on when I've tested sound 
performance). After I recompiled the new kernel the sound didn't skip 
anymore, but now after 10 hour uptime and 5 hours of mp3 playing the 
skipping is back. The skipping is like every second there's a weird noise 
if I listen to something, like the track would go slower for 2/10 seconds 
of every second, you can imagine how annoying this can be.

IMO it feels like some buffer is full or something and then it starts the 

My system:
