I downgraded to 2.6.31.5-127 and I still have the same issue. The odd thing
is that the slider volume control on my keyboard still "works" in the sense
that the computer knows to adjust the volume--but it just goes to a dummy
output device. I notice that the hda-related modules aren't loaded, so I
tried loading those. No success there, however. It might be useful to note
that I was trying to get a USB TV tuner to work earlier--in so doing perhaps
something went wrong with the sound modules.

Hi Emerson,
It sounds like you have a kernel issue. Do you remember when the sound
stopped working? If you do, and you have multiple kernels installed, I
would try booting the system with an earlier kernel
(Command line: rpm -qa --last kernel ).
See if that fixes the sound issue. Good luck,, and let us know (or
file a bug in bugzilla under "kernel")
