This is a known problem in FC3 with a large number (but not all) sound
chips. I can happen in FC2 as well if you upgrade to a 2.6.10 kernel.

The basic problem (at least for my chips) is that certain mixer settings
are not getting set to sensible defaults. And even if you finally get
them set correctly yourself, an actl save/restore cycle (as when rebooting)
doesn't restore them correctly.

You can usually get it to work just by finding that mystery mixer setting
that's getting in the way. For the chip on my laptop it's the mixer's DAC
switch. On my HTPC it's the input capture selector.
