Hi there Gene.

I think I'd disable Pulseaudio temporarily, and you can do that by just 
removing the package, alsa-plugins-pulseaudio. If your using KDE, removing 
that package will also remove the kde-settings-pulseaudio package. You can 
always reinstall them later, but IIRC Pulseaudio has problems with multiple 
cards, but I may be wrong there.

Can you post the output from a few commands, as below.

cat /proc/asound/cards
cat /proc/asound/version
grep ^Codec /proc/asound/card?/codec*
/sbin/lsmod | grep snd


If you leave Pulseaudio enabled, alsamixer only shows a single control, but 
you can get to the controls for the individual cards (presuming they all show 
up in /proc/asound/cards), by opening alsamixer on the CLI, as below.

alsamixer -D hw:0                (that's for card0)
alsamixer -D hw:1                (for card1, and so on)

You may need to set a model option for the onboard card in /etc/modprobe.conf, 
to get the necessary mixer controls to show up in alsamixer, or sometimes a 
model option is necessary just to get the card detected. Post back the stuff 
requested above first, as we need to know the codec that the hda intel card 
uses, so as to know which model options to try.

My Asus M2N-X Plus board has sound working out of the box, but to get a CD 
slider showing in alsamixer, I have to set a model option as below.
options snd-hda-intel model=3stack-dig      (just an example)

I do have Fedora 8 on the machine with this mobo.

All the best.

Nigel.
