I recall doing this on Fedora 14 for my HTPC so it should be similar or
at least point you in the right direction. I wrote something for it
(GeForce 210) here:


I remember having to update the alsa-driver package to something newer
than what was default via ATrpms repo. I believe you need version 1.0.23
or newer for it to work (version can be checked by looking
at /proc/asound/version).

Then I had to go into alsamixer and unmute the line.
