With the latest two kernels (2.15.19 and 2.15.20), when I start jack using qjackctl, it immediately starts reporting xruns at the rate of about 10 per second - and this is with no applications running at all.

It's possible that they used to use realtime-lsm and recently switched to the rlimit approach (although, shouldn't JACK bomb out if started with -R and realtime scheduling is unavailable, rather than failing silently?). Try adding this to the end of /etc/security/limits.conf: * rtprio hard 99 * nice hard -20 Then reboot and try it again. If it still fails please post the JACK output Lee
