After comments by Neils and Jeremy, I went rummaging thru the drawers,
and found an old soundblaster, So I disabled the onboard audio, and
plugged in the soundblaster:

...I then opened another console, and checked dmesg and /var/log/messages.

dmesg had no apparent references to audio, but I found this at the end of
/var/log/messages:

...while jackd is running, desktop audio seems to be suspended. At least
I get no output when I sample the various sounds in
System/preferences/sounds.

...I stop jackd with ^C, it stops cleanly, and desktop audio is
re-enabled!

...I start Ardour, and select my 'test' session. When I click 'open', it
gives me a message about 'I must select a device first'. I poked around
the various tabs, and under 'device' and 'advanced', I found input and
output options that were blank. It offered me choices of 'standard PCM'
or 'Multichannel'. I selected the 'Standard PCM' for both input and
output, and then Ardour was willing to open the session.

...cross my fingers, and click on 'play'. The playhead moves, I see
signal in the level meters, but no sound. I notice that the output
selector on the master bus is '-', so I click on it and select 'out 1-2'.
A good sign, '1/2' is displayed on the output selector. Press Play
again...

Success! It actually gives me sound.

Save the session, close Ardour, and check with ps. Jackd isn't there!
Check desktop sounds - they're enabled again. So far, so good.

Next steps: Hook up the firewire interface and see if it behaves with
ffado...
