As statesman said we don't have enough to go by. If you'd care to put your card in and try it again. Then post the new debug.err that was generated with the sound card and its drivers. We would have more to go on.
How much do you value you the sound card? I mean you can get a halfway good one at Wally (Wal-mart) for around $30, I picked up a SoundBlaster 24bit there.
