Sounds like a reasonable supposition.

Could you post the contents of /etc/alsa/modultils/1.0 please?

Did you notice anything else get upgraded at the same time? This shouldn't 
have caused any problems.

Try moving the soundcard to a different slot - which device is it sharing with 
here?

This is interesting, I've no idea what it means. Do you have the right version 
of alsa-modules installed?

This is normal, you haven't installed the pcmcia modules, presumably because 
this isn't a laptop. You can ignore these warnings.

All this means is that you don't have ALSA configured correctly, you knew that 
already. It should be fairly easy to sort out.
