[PlanetCCRMA] Can get jackd to run

[David Slimp]

Not sure I can help much with this one...

What sound card are you using?

If that is a 500MHz machine... is it possible your settings
are too demanding to keep up?  (are you seeing xrun messages?)
Try a lower sample rate - not 48000.
Try a higher Frames/Period - not 512.

Have you looked at the jack website/FAQ/HowTo/docs:
http://jackit.sourceforge.net/docs/

Have you posted/searched the jack mailing list?
http://sourceforge.net/mailarchive/forum.php?forum_id=3040

... not trying to avoid your question, but more people on
the jack site can probably answer jack questions faster, and
might have more experience with how to debug problems.
(good to ask/look in both places)
