This means you don't have realtime privilege and cannot start jack in
realtime mode.
If you chose "yes" to have realtime capability while installing jack,
you will have installed a file /etc/security/limits.d/audio.conf, but to
make use of that file you need to be a part of audio group.

Group changes take effect after logging out/in.
