Is XMMS with the JACK output driver working for you? That's my standard JACK test...but...if qjackctl isn't working...I doubt the problem is with Pd. Sounds more like a problem  with jackd. When messing with JACK initially, I always find it easiest to run jackd or jackstart from qjackctl. Easier to debug what is going on.

Is the output below from jackd or qjackctl? Whatever it is...it isn't happy. That's the place to start.

Hello everyone!

Sorry to be a drag here, but I've been scratching my head on this for several days now.  I'm trying to coordinate pd, alsa, and jack on ubuntu (actually demudi multimedia kernel 2.6.12 in ubuntu) and I've got a number of symptoms here, but I've not been able to diagnose what's going on:

- not getting any sound from pd; pd doesn't recognize any devices
- pd's Media menu lists 'OSS', 'ALSA', and 'Jack'
- compiled pd 0.39-2 with --enable-alsa --enable-jack
- alsa seems to be installed fine, alsamixer works, cds play in alsaplayer
- qjackctl will not connect to jack server as client - but jack appears to start fine (?):

13:44:26.950 JACK was started with PID=6255 (0x186f).

So I was wondering, anyone have any pointers here?  I'm stumped.

Thanks,
