Yes, that's where I got the info that it isn't available.

Yes, my one slider is up all the way, not muted.  I'm beginning to
think, "hardware."

As luck would have it, Intrepid's grub has not only failed to list both
my old kernels on the existing partitions, it has also failed to list
the other bootable partitions in my system.

I think I'll slide in the Intrepid CD and boot live to see if it has
sound.  If not, maybe hardware?  I'm running out of resources!
(me, not the system)

Hmm, there's an upgrade today for libasound2-plugins which looks like
it may be what I'm waiting for.  Here's some description:

ALSA library additional plugins
This package contains plugins for the ALSA library that are
not included in the main libasound2 package.
[...]
The PulseAudio library plugin "pulse" allows the ALSA
library to play or capture via PulseAudio.

I'm off to try it.
