Public bug reported: I discovered this in relation to jack, which installs /etc/security/limits.d/audio.conf, containing:
@audio - rtprio 95 @audio - memlock unlimited For a user in the audio group: $ulimit -l -r max locked memory (kbytes, -l) 65536 real-time priority (-r) 95 So jack (run as user via qjackctl) reports: ERROR: Cannot lock down 82280346 byte memory area (Cannot allocate memory) but does not report that it cannot set real-time priority, which it does if run by a user not in the audio group. I also tried putting the line in /etc/security/limits.conf, and trying a number rather than "unlimited", but it didn't help.
