Hey all, I am experiencing some clicking/popping noises when running Jack on my both my internal and external USB interface. Oddly this did not coincide with the usual culprit, XRuns. I tracked it down to some errors in the system logs. Dec 23 23:10:37 defiant pulseaudio[4011]: module-jack-sink.c: JACK error >Cannot use real-time scheduling (RR/75)(1: Operation not permitted)< Dec 23 23:10:37 defiant pulseaudio[4011]: module-jack-sink.c: JACK error >AcquireRealTime error< Dec 23 23:10:37 defiant pulseaudio[4011]: module-jack-source.c: JACK error >Cannot use real-time scheduling (RR/75)(1: Operation not permitted)< Dec 23 23:10:37 defiant pulseaudio[4011]: module-jack-source.c: JACK error >AcquireRealTime error< Looks like pulse is having trouble with realtime permissions/scheduling?? I am fairly new to the pulseaudio-module-jack package(Ubuntu) that supplys module-jack-sink and module-jack-source for Pulse/Jack integration.
