iirc, you should use the same user to start jackd and Pd. so if you run Pd as user "chi", than you should also run jackd as user "chi". the same if you use root (which i don't recommend; you should rather fix your /etc/security/limits.conf to be able to run realtime processes as member of the audio-group).
Thanks..
I've resolved the problem of "user" adding (as root) those rows in /etc/security/limits.conf:
@audio - rtprio 80 @audio - memlock 288000 #288000 because my RAM is 576 MB @audio - nice -10
and I set user in "audio" member group. _______________________ In JACK setup I set: realtime, priority 80 midi driver: seq _______________________ So now I can open qjackctl and start JACK correctly (play), but give me this error:
cannot use real-time scheduling (FIFO at priority 90) [for thread -1238557840, from thread -1238557840] (1: Operation not permitted)
Now I open pd, and in "media" I select: JACK, and ALSA-MIDI.
Then I open JACK connections: I see 2 windows: AUDIO and MIDI. Here, in both windows, I connect pd with my SB LIVE! sound card. ____________________________________________ Now, running some patch in pd, happen this:
1)in a audio patch (for example a simple oscillator with a slide..) *I can listen sound correctly* (even if with a fastidious background noise) and I can change frequency well with the slide.
2)in a midi patch (a patch certainly correct, tested in o.s. Windows..!) *I can't listen anything*. I see numbers change, but *no sound*.
PD give me this error:
audio I/O error history: seconds ago error type 1.39 A/D/A sync 3.25 A/D/A sync 3.28 A/D/A sync 3.37 A/D/A sync 3.38 A/D/A sync (..etc..etc..similarly)
Thank you in advance, cb
