Sources and sinks, yes. Well, they should show up in both PulseAudio

should be able to route it the way you want in both PulseAudio and JACK.
If you have both Natty and the DBus version of Jack2, it should show
up automatically. If you use Lucid, Maverick, or Natty with another
version of Jack, you'll need one or both of terminal command(s):
pacmd load-module module-jack-sink
pacmd load-module module-jack-source
...depending on whether you want to link playback, recording, or both.

David,
Okay, did some testing tonight but had some trouble.
Since qjackctl has the wrapper script to suspend Pulse Audio I shied
away from it,
Hmm, is that script still present? AFAIK it was removed in Maverick,
when PA and Jack implemented the device reservation protocol.
although I realize that I could have called the binary
directly and skipped the script. However, I did it from the command line.
If I just run "qjackctl" from a terminal here, it does not suspend
PulseAudio.
Firstly, I checked the jack version [1], which appears to be correct as
it is jack2 and in Natty.
For the automatic stuff you want to make sure that Setup -> Misc ->
"Enable D-Bus interface" is checked as well.
My first test was to start playing an .ogg file with Totem and then try
to start jack from the command line. The result was that jack found the
hardware locked...Ptui! Ubuntu pastebin isn't working, sorry for the
wall of text:
scott@natty-studio:~$ jackd -dalsa -dhw:1 -r44100 -p512 -n3
...and start "jackdbus" instead of "jackd" here.

Hmm, under this scenario, could you supply the output of "sudo fuser -v
/dev/snd/*"? It sounds like totem does not use pulseaudio but goes to
the sound card through some other path.
Now, I reversed the process and start jack from the command line and
then try to start Totem with the .ogg file:

This started jack well but Totem refused to play the song. When I ctl-c
to stop jack then Totem started up directly and began to play the song.
At this point I didn't try either 'pacmd' lines until I hear back from
you as it seems you expected this to work. I realize, however, that
there is a real chance that I'm doing something wrong too :)
Could you also check
1) the "Connect" window in qjackctl and see if there are PulseAudio
sources and sinks there?
2) in the "pavucontrol" application, check that "Totem" is set to output
to the Jack sink?
Maybe they just need to be connected manually?
