Sound problem

[CAVELIER Grégory]

First, thank you for your answers about "CPU frequency".

But I have another problem: When I play something through XMMS I 
sometimes hear some little "plop" (Don't know how to explain that). It's 
like my PC is overloaded but it's not...

I've "renice" XMMS to priority -20 but it doesn't change anything.

Any ideas ?

I've have FreeBSD 5.2.1 and a SB AWE 32 ISA working with module snd_sb

Thanks
