howdy, i just recently upgraded from my old crummy soundblaster live value. while i anticipate my new m-audio revolution sounding much better, at the moment it's driving me crazy because whenever i record i get this poppy scratchy sound during playback. i'm sure thish as something to do with a sync error between the card and computer. i've updated the drivers, so it's not that. please lend me your support if you have had similar problems with your own soundcards. it's not imperative that the soundcards are identical, as there may be a universal way to fix this sort of problem.
