...continuation of my adventures with Fedora12 + CCRMA:
OK, so I rebooted to get rid of the zombified jack.
I again launch qjackctl, and press the start button.
Progress! No SELinux messages, and jack starts up.
I launch Ardour. It presents a window new to me, asking about 'audio
setup'. I leave it at the defaults, and press 'start audio engine'. It
then tells me that jack is already running as another user. Doh!
So I think "Hey, they've improved Ardour, so I no longer need to use
qjackctl to get jack started first. Why won't they connect to an
already-running jack, though??" I close Ardour.
I go back to qjackctl, and press 'stop'. The display changes from
'started' to 'stopping'. I wait. Nothing more happens, and it appears
that after all the trouble getting jack started, now it won't stop!
...another reboot. This is not acceptable. It's looking too much like
another OS I hate...
Now I launch Ardour, and let it start jack for me. I open a little test
session containing only a single short track. I press the 'play' button,
and nothing happens. I try hitting the space bar, and nothing happens. I
click on the timeline, and the playhead moves as expected. I press the
'return to zero' button, and nothing happens.
This was a session recorded with another version of Ardour (on US 10.04),
so I think it might be a compatibility issue. So I stop ardour, and then
re-start it to open a new session and try that. It gives me a message
that it couldn't start jack because it was already running as another
user. This jack won't die, either:

...I'm getting pretty sick of these reboots!
