No, that wasn't the problem. The problem is that my snd_intel8x0
has the "master" and "headphone" wires swapped (common problem).

I fixed it by adding this to my /etc/modprobe.d/alsa-base:

options snd-intel8x0 ac97_quirk=1

And rebooting. Now my sound works fine.

BTW, I'm using ALSA with OSS emulation. I tried using ALSA
without OSS emulation, but I kept getting an error in my mythfrontend's
logs stating that myth was requesting a 0hz stream. This seems to be
a common problem with MythTV 0.18.1 as I saw another unresolved
post about it from Jul 2005. Someone claimed it was fixed in CVS,
but I'm not going there. I'll stick with OSS emulation for now.
