Setting positive nice values works though, even values beyond 39 (which as I understand is the maximum valid niceness?).

Jack Error Cannot Use Real Time Scheduling However, many if not most Linux distributions do not allow applications run by ordinary users to request RT scheduling by default.
The realtime module is loaded with 'dmesg | grep -i realtime' yielding: Realtime LSM initialized (all groups, mlock=1) When I try to start JACK audio server in realtime mode (via qjackctl) http://sonoportal.net/cannot-use/cannot-use-real-time-scheduling-fifo-at-priority-99.html This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. For example: #!/bin/bash ulimit -r 99 su myuser /usr/bin/jackd -R -P89 -dalsa -dhw:0 -r44100 -p128 -n3 Regards, Bob. All of these settings should be taken care of automatically.

Is the 'getrlimit returned 0' in the last three lines a problem? First I tried set_rlimits, with /etc/set_rlimits.conf containing the line Code: @audio /usr/bin/jackd nice=-1 rtprio=80 memlock=100000 and myself of course belonging to the audio group. I also ran this program I found somewhere on the internet, it's supposed to check for realtime permissions, Code: #include
If your system is not setup correctly, then JACK will print a message like when it tries to run with RT scheduling (it will appear in the messages window of QJackctl If you follow all these steps carefully and they do not work, you should review the information over here and consider whether this may apply to your system. If this group name already exists, pick a different name and use it instead of “realtime” when following the rest of these instructions. his comment is here It's interesting that the ccrma kernel is not recognized as a realtime kernel by this script.
