Sound card no longer working. FC7 2.6.21

After an upgrade to FC7, I enjoyed weeks of blissfull sound-filled computation, but now all of a sudden, it no longer works! I get this error when starting the volume manager:

No volume control GStreamer plugins and/or devices found.
system-config-soundcard feeds back my soundcard correctly, but lists no PCM devices, I've never used it before (soundcards always worked) so I don't know if thats relevent or not

lspci shows:

00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller (rev 60)
looks like the card is fairly well recognized, maybe a driver issue...I just finished updating the system and included in the packages was a few ALSA updates, I hoped they would fix it but alas, they did not.

Thanks to everyone!

yikes! Thats looks nothing like it usually does...theirs like nothing there! I'm not seeing anything for the sound card either...but after some research I can't find what it wants.

(Info that might be useful...)
Notice the rt2570 at the top? Thats for my wireless card, and to get that to work I had to blacklist 3 modules (rt2500usb, rt2x00usb,rt2x00lib), seems impossible, but that wouldn't have anything to do with this would it? The problem might have started right after doing that, I don't know. I didn't notice the problem for awhile.


I updated to kernel 2.6.22, and sound worked.


Internet does not. I write this from the old 2.6.21 with no sound. The folder "/lib/modules/2.6.21-1.3194.fc7/kernel/" which on 2.6.22 has a bunch of folders, has nothing. I assume that is the source of all the problems, but where did it go!?!?

Seriously, literally nothing, what could have happend...
