I had a bit of a hack around with module options to see if it was the
soundcard output bitrate or anything, but with no luck. I tried setting
the output bitrate explicitly to 44100Hz, but then everything noticeably
slowed down - pitch changed and everything, but the timer on MythMusic
still ended a few seconds early, just as before, so I put it back.

I'm using the built-in AC97 sound device using the ATI IXP driver, so I
put this in modprobe.conf to change the bitrate:

options snd-atiixp ac97_clock=44100

If you're not getting pitch shifting though, I guess this isn't your
problem either...

cheers,
