Does the jackuser group in Fedora, play the same role as the audio group in other distributions? If that is the case, why do the parameters in /etc/security/limits.d/95-jack.conf diverge so much from the suggested parameters in the Jack Audio FAQ? The FAQ recommends setting realtime priority to 95 and memlock to unlimited, whereas the 95-jack.conf file has settings set to:
@jackuser - rtprio 70
@jackuser - memlock 4194304
The memlock number looks quite weird…
