hi,
i don't use pd-extended, but i think it's almost the same. the only option missing is: -nosleep (useful for dual-core).
so be sure in qjackctl - setup: Realtime Periods/Buffer: 2 Sample Rate: 44100 (or more) Frames/Period: 256 (i am running at 64 without glitches)
then for pd: pd -rt -jack -r 44100 -nosleep -audiobuf 256 -channels 16 -alsamidi -mididev 1 etc...
and finally, be sure to edit /etc/security/limits.conf: @audio - rtprio 99 @audio - memlock unlimited @audio - nice -20
and of course, add yourself to audio group (reboot to be sure). let us know.
ah yes, a long time ago i was using icewm, because gnome was causing glitches in pd. but now it seems ok here.

Hi
I get clicks and "DIO errors" at random intervals under linux/ubuntu with jack (no xruns). I have a 17ms latency setup with jack and a realtime patched kernel and the rest of my audio setup works great with jack.
I installed pd from Pd-0.40.3-extended-20080628-ubuntu-gutsy-i386.deb
Any one else running a similar pd with a similar setup and either have it working or experience the same problems?
