I think i broke my soundcard(the one that comes built in the PC). I plugged my guitar into my amp and from the headphone jack of the amp into the PC. I didn't think it would inflict permanent damage but it did. I take this as an oportunity to upgrade my sound card because now mine is hissing alot. Anybody know of a sound card with an XLR jack for a mic and(obviously) an output??? I dont do multitrack so one channel is good enough... anyone know? thanks!
