It only happens with music > (mp3,ogg). I tried a sound card with a CS4630 chip and still got the same thing. Strange that it takes a while for the noises to appear. Anyway, I was fiddling with settings using XMMS to play mp3's and found changing either "resolution" from 16bit to 8bit or changing "down sample" from 1:1(44khz) to 1:2(22khz) fixes the problem. These settings are located under audio i/o plugins -> input plugins -> mpeg layer 1/2/3 player -> configure -> decoder. Also after using these settings (1:2(22khz)) for half an hour and then changing them back to defaults ... sound was good. I should add that running gkrellm (/ports/sysutils/gkrellm) _and_ having the cpu monitor enabled makes the noises much worse. Again, on my system this only occurs after several hours and of course if I reboot all is well. If nothing else at least I've found a way to avoid rebooting, I guess.
