Fedora 11 lost sound during yum update

I have Fedora 11 running on a Compaq Presario SR5710F. When I installed Fedora 11 last summer I had a lot of trouble getting the sound to work right but eventually I got it working albeit not perfectly (often I couldn't get sound on reboot).

The sound was working when I did a yum update but the sound quit during the update. (possibly when mplayer was updated) I rebooted and got some sound -- kplayer worked but mplayer did not. But on the subsequent reboot there was no sound nor Kmix (Kmix is blank). I've re-installed alsa and pulse.

aplay -l returns : "device_list:223: no soundcards found..."

lspci -v gives
"00:05.0 Audio device: nVidia Corporation MCP61 High Definition Audio (rev a2)
Subsystem: Hewlett-Packard Company Device 2a5c
Flags: bus master, 66MHz, fast devsel, latency 0, IRQ 255
Memory at fe028000 (32-bit, non-prefetchable) [size=16K]
Capabilities: [44] Power Management version 2
Capabilities: [50] MSI: Enable- Count=1/1 Maskable+ 64bit+
Capabilities: [6c] HyperTransport: MSI Mapping Enable- Fixed+"

The sound card exists and is viable but linux just can't see it. (it worked a single time right after the update) One thing I keep wondering: what exactly does the OS (sound driver) look at to find the sound card?

I sure hope some sharp techie out there can help me fix this thing, I'm out of things to try.

P.S. ALSA information is located at
