Last night after I instaled my 1394 card, vegas wouldn't recognize it. So i decided to do a fresh instal of vegas. But when I got started again, my audio settings were buggy. The audio is choppy and full of artifact...WTF!!! I have a high end edirol audio card, and have been using acid to do music with for years without a glitch...! Now even acid is having the same problem....what should I do? I've tryed re-installing the drivers for my sound card 3 or 4 times and it's not doing anything...I haven't changed any other settings...I fear I may have to do a fresh windows install....:-(
