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. --- snip --- the only difference is that i don't experience the looping sound problem. the sound card i have is a sound blaster live 5.1 and i've also tried a hercules muse xl, both of which experience the problem after several hours of operation. i've tried the gkrellm quick fix and disabled several krells that seems to help. the downsample thing seems to work too. i'm just wondering if there has been any development on this issue since 5.2.1-RELEASE (what i'm currently using). here is a full list of my hardware: - AMD Duron(tm) Processor @ 1.2GHz - 128MB PC133 RAM, 256MB PC133 RAM, totalling 384MB - 4.3GB Fujitsu hard drive (Ultra-ATA 66) - 20.2GB Maxtor hard drive (Ultra-ATA 100) - 50x max IDE CD-ROM drive - 40x12x48 LITE-ON CD-R/RW drive - SiS 7012 PCI sound card (integrated, disabled) - Creative SoundBlaster Live! 5.1 - GeForce 4 Ti 4200 w/64MB DDR VRAM w/TV-out (latest nvidia drivers - SiS900 10/100 ethernet card (integrated) thanks, - ryan
