It is set to 44.1 from the hardware side. Qjackctl starts it thusly: /usr/bin/jackd -dalsa -r44100 -p1024 -n3 -D -Chw:1 -Phw:1 (taken from ps ax | grep jack) I can run it with lower latency when I need to but I don't push it for my simple daily recording. I have used ardour with it but these days mostly use traverso as my needs are very simple for my daily stuff. uname -a gives Linux zriven 2.6.24-24-rt #1 SMP PREEMPT RT Wed Apr 15 18:09:25 UTC 2009 i686 GNU/Linux > Kindest regards > Julien > all the best, drew _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
