I've included a portion of the jackd output below. > just a way of clarification. the RT blinking is a recent "feature" of QjackCtl. you can turn it off in the Setup/Display/Blink server mode display option if you don't like it :) the RT indication being there, either blinking or not, is a simple indication that the jack server is running in real-time mode. the blinking is just some lousy eye-candy, nothing more, nothing less ... it just happens that qjackctl displays new xruns and blinks at the very same time (~2 second period). the xruns are happening in between (and count reported as "skipped") it just doesn't matter whether the RT indicator is blinking or not. byee -- rncbc aka Rui Nuno Capela rncbc@xxxxxxxxx _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
