	I've never tried playing guitar through my computer but I spent a
long time recording TV programs with a BT878 tuner card with it's audio out
plugged in to the aux in of my sound card (I put the bktr support into
ffmpeg for the purpose). I was always able to get recordings with really
good A/V sync using FreeBSD or DragonFly while I also read reports of A/V
sync problems under Linux/ALSA and heroic work being done to try and sort
them out.

	This leads me to ask - have you ever tried playing a guitar through
the DragonFly or FreeBSD sound system because it seems to me that the
video recording A/V sync problem is about as demanding ?
