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.
