    Well, it seems to be working now.  I mounted my home partition from the 
US10.04 system, and began to wander thru it looking for .wav files.  When 
I encountered one, as soon as I hovered the mouse over it, I began to hear 
the piece coming from my speakers.

   I then went to the 'sound' preferences panel, and clicked on the various 
alert sonds presented there.  Each one played itself just fine.  This 
particular exercise is the one that 'confirmed' to me that it wasn't 
working an hour ago.  No changes since then other than a reboot.

  I got around that by booting from the US10.04 DVD and selecting 'rescue', 
then re-writing its MBR to the second HDD.  Now I can use the BIOS boot 
menu to select which HDD to look at, and I've got a triple-boot system 
again.


Moving on -
   I launched Ardour, opening the 'test' session I had started earlier.  I 
imported a stereo .wav file into a new track, and attempted to play it. 
Same as before:  clicking the 'play' button does nothing.  The playhead 
doesn't move, clock doesn't count, etc.  This time, however, the 'go to 
start' and 'go to end' buttons do work.
   When I try to close the session, Ardour locks up completely.  The 
'session' menu doesn't even disappear...

top shows me that ardour is still grabbing some cpu cycles every few 
seconds, but jackd doesn't show up at all.
`ps aux' shows me this:
