Hi Robert,

I'm having problems with Pure Data and JACK and I
was wondering if anyone
else has seen this behavior.
I can have any number of JACK applications happily running and routing
audio back and forth, when I start PD I often (but not always) get a
crackly distortion. This distortion is present is on any JACK client,
before PD has even loaded a patch or is actually processing audio. Closing
PD does not solve the problem,. I need to close every JACK client, close
jackd, and restart the server.
I remotely remember something similar a while ago on one of my boxes,
yet not sure if i had gotten the same error messages as you. But I had
to restart my jack server as well (and hence all clients that were
connected to it).
Somehow I ended up setting jackd's priority to 89 (using the qjackctl
GUI). Not sure if it was due to that error or for other reasons.
Try using pd -rt -jack (realtime priority in Pd) and ask on the Pd
mailing list as well: http://lists.puredata.info/pipermail/pd-list/
best, P
