OK. I am just using whatever is default from apt-get and the 
autodetection found.

Didn't I already listed that earlier with uname -a? Oh well, here:

$ uname -a
Linux ANTian 2.6.18-3-k7 #1 SMP Sun Dec 10 20:17:39 UTC 2006 i686 
GNU/Linux
$ uname -r
2.6.18-3-k7

Should be the latest from unstable?
$ cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.12rc1 (Thu Jun 22 
13:55:50 2006 UTC).

Also, I ran apt-get update and upgrade today.

Isn't this the same as rebooting Debian/Linux? I ran these two commands 
as you requested:
# /etc/init.d/alsa-utils stop
Shutting down ALSA...done.
# /etc/init.d/alsa-utils start
Setting up ALSA...done.

Yes, see above.

BINGO! I think I found it and I know what I missed.

There are four VIA DXS (what the heck is this?) in mixers. I cranked the
most left VIA DXS and it worked!! Man, these labels aren't informative.
What exactly is VIA DXS???

Yep, and I discovered this command.

Not anymore, but I hope they see the issue with VIA DXS labels. How 
would I know these did something and what they did. :)
