Hi Josh, Scheduling JACK to run with realtime priority (using the -R option) is separate to having a kernel that runs with hard realtime pre-emption enabled. Ideally, you want both, but on a vanilla kernel, you still want the -R option -- indeed, that's how I run my systems. One way to think of it is that running with realtime priority (with the -R option) instructs the kernel to run JACK with the best scheduling it can possibly manage. If you also have realtime pre-emption in your kernel, though, then the kernel's best effort will be... well, better :) Thanks Leigh _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
