This is getting interesting.  I do not have a /dev/snd directory.  I tried 
reinstalling the devs rpm package, and that recreated /dev/snd, but after a 
reboot /dev/snd was gone again.  

Here's something else I tried.  If having the driver loaded is the problem, 
then the problem should go away if I remove it.  So I did

rmmod snd_via82xx

which succeeded and caused the entry to disappear, as verified by

lsmod | grep via82

I then retried the Yast installation and got the same error as before.  After 
that attempt, though, the previous command gave me

snd_via82xx            32920  0

indicating that the Yast installation restored the module.  So I would guess 
that the module is loaded but is not usable because of the problems indicated 
by the original error message (at the beginning of this thread).

I also tried alsaconf again and got this, as before:

Loading driver...
Starting sound driver:  via82xx                                       done
/usr/sbin/alsactl: load_state:1236: No soundcards found...

which suggests that even though the driver is loaded, it cannot access the car 
(actually part of the motherboard).
