[Csnd] Csound5 and Jack on Mac

Hi there,

I just posted this on a forum but I thought I'd try the list as well,  
hope that's OK.

I am (rather inexpertly) trying to get Csound 5.01 (downloaded from  
sourceforge) sending audio to other applications via Jack.

I've used the -rtaudio=jack flag and it compiles OK but when I press  
play I get this:

WARNING: rtjack: xrun in real time audio

which repeats indefinitely.

Jack seems to be working OK as I can send audio from itunes to cubase  
etc.

I'm on OSX10.4.5 on a G4 powerbook, if this helps.

Any ideas? Many thanks in advance

Well, I followed the instructions as best I could from the  
documentation which came with Jack when I downloaded it a few days  
ago. The instructions included "Jack-Enabling" the applications,  
which worked with Cubase and itunes - they appeared in the jack  
"router" and I'm able to send music from itunes to cubase without any  
problem.

When I compile some code with the -+rtaudio=jack flag enabled, csound  
also appears in the router, so it looks like everything is running  
smoothly. In fact, the instrument appears to be working (apart from  
the repeating warning message) as it is receiving MIDI messages OK  
and playing notes, but no sound.

I'm not a programmer so I could easily have made some simple mistake...

I hope this helps answer your question,
