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
