Moving to a different USB port fixed it. Perhaps it was just restarting the machine and interface?

A lot easier than digging in config files or JACK settings :) _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
