Ok, several responses to various recommendations/ideas are included here.. first off.. I installed sox and performed the suggested downsampling. I took a 44khz wav file and converted it to 38Khz, 22Khz, and 8Khz... all wav files prdouced the same screeching as the 44Khz one. Next, I recompiled mpg123 and my kernel with i386 instead of p2 in make.conf. That made no difference. I built my system up from source. After an initial 'bare' console install, I did a cvsup to get /usr/src and /usr/ports, made world, made the kernel, made X, etc., all using the optimizations I've mentioned. I do everything 'properly' if you will, so for the kernel I started with the GENERIC file which I modified based on reading LINT and various documents, and I compiled it using 'make kernel KERNCONF=MYCONF'. As far as I know, I have done everything 'according to the rules.' As I've said, 2 of my friends run the exact same card under 4.5 with no problems... but let's not forget that my SP 64 (es1370) experiences the same problem. It _could_ be that my clock is fast, but that would be odd... my system was pretty good back in 98 when I built it.. just in case any of this means anything: Asus P2B w/ P2-450 Matrox G200 256MB ram Promise ATA/100 Controller -> IBM Deskstar 20 gig, 7200 (BSD's Home :)) Various other driver, nics, etc. The box has been humming flawlessly since I've put it together, with almost no down time (other than moving from apartment to apartment). It ran Win98 fine back in the day, then housed Linux for 2+ years... I figured I'd have seen problems if there were any serious ones. Sorry to all those who don't give a crap, I didn't mean to spam this list with my rather minor problem, but I don't really know who else to turn to :\ - Adam On Fri, 29 Mar 2002, John Utz wrote: ::On Fri, 29 Mar 2002, Adam D.
