Hmm, is it some crackling sound whenever you play something ?
If so, does it increase with increasing HDD or network load ?
Which board/chipset is this ? Maybe VIA or SiS 735 ?
My Aztech PC168 has such crackling sound problems on my ECS K7S5A board
(SiS 735 chip), and the chip has quite a history of DMA transfer issues
with soundcards.

Try inserting the card into a different PCI slot. Could make
one hell of a difference.
