Well I just d/l'd a live-cd version of SLAX and verified that my mobo
sound hardware hadn't gone tango-uniform, so I'm back to trying to
figure out what happened.

I'm obsessing over these lines in my /var/log/messages:

Sep 20 12:45:43 gmj-mythtv modprobe: FATAL: Error running install command for sound_slot_1
Sep 20 12:45:58 gmj-mythtv modprobe: FATAL: Error running install command for sound_slot_1 
Sep 20 12:46:14 gmj-mythtv kernel: application sox uses obsolete OSS audio interface

Is that implying that modprobe is trying to install a driver for a
sound card that doesn't exist? How do I determine that?

I also noticed that the last apt-get upgrade installed new ALSA lib
and utils (1.06), but did not install the driver code (1.06a). Could
this be the problem?
