I tried as root to have a better nice, no change. Maybe it's not a jack issue, maybe it's the bad configuration of another part of the system. It's ubuntu 10.10 with no customization except removing pulseaudio. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
