i notice capturing through my USB my sound comes out like a low bps mp3 file, it has some techy grainyness to the sound, its not clear or perfect, it sounds compressed, but I think its from using USB2.0 ... in your case, i would turn down the audio input, because you can always increase it, it is digital! I'm assuming your audio comes in on the firewire card? did you try pluging in the a/v cord to the camera and pluging the video end into the line-in on your sond card? Its a bit more work than just doing it all at once but if fixes your problem, well then there you go! I would think snycing the vid and aud would be a problem, I wonder if there is capturing software that opts for the LINEIN versus the firewire card for audio and syncs it. Or have you done all this already?
