I just installed the CentOS appliance CD. Jack wouldn't start when
starting the default rivendell service. I had to setuid (chown rd) caed
to the running user. Then use qjackctl to autostart jack. Caed now is
started when any rivendell app is started. The rivendell service is
disabled.

Rob,
The biggest issue I've run into with Jack not starting usually get down
to a few things:
-Something else has already grabbed the sound card (Pulseaudio - while
it can be made to co-exist with Jack - is bad for this)
-Some sound cards (especially USB based sound cards) that won't work
unless you force Jack to use 16-bit mode with the -S parameter
-Sample rate mismatches and sound cards that only like to run at one
sample rate
-Some sound cards only like the periods / buffer setting to be 2, some
only want it to be 3, and others are fine with anything you give it
-The user running Jack not being a member of the audio group (and some
systems don't let you run Jack in Realtime mode, but this is usually a
setting in limits.conf that hasn't been configured properly)
Between the above I've managed to get Jack to run even on the pickiest
systems. But I admit that sometimes it can take several tries to figure
out where the difficulty is and / or what settings will work reliably.

I'mno against JACK, I only wish it were better documented. Why will it
refuse to start at all on some machines but give no trouble on others? The
oracle at Googlephi does not know, and can only give me vague warnings
about geeks bearing .gifs.
