Well I know that thing as it occurs here too.

no reason to argument ;). If you want do so, you should be able to do 
it.

Yep high frequent noise. As it was pointed out I think that this comes 
if more then one sound is played. On my system it was often caused by 
aplay that plays the system sound then mail has arrived. ( I have 
switched this crappy artsd off on my system. )

On my system a 'service alsa restart' has fixed this issue all the time. 
If you have arts running and a relogin fixes it, it may be arts. It is 
interesting tough, since I thought all the time it is a bad soundcard 
driver. I have a Terratec DMX Fire 1024 using cs46xx driver and with 
the switch from 9.0 to 9.1 it got a lot better, with 9.2 beta1 I have 
the feeling sound is even better again, but that may be subjective. On 
further problem I may have here is that I have some dma problems (not 
enough bandwith on pci I guess, caused by my dvb card and sound card 
and high system load => cdrdao cue-burning ) Never had such things with 
the onboard sound, but the Terratec sounds so much better i stay with 
restarting alsa ;) 

short: Possible fix: switching off system sound ;)
