I've read other posts and I cannot find any suser-j.engelh repository to get kernel-rt. I get this error when I try to start qjackctl:
12:50:18.709 Patchbay deactivated.
12:50:18.714 Statistics reset.
12:50:18.715 Could not open ALSA sequencer as a client. ALSA MIDI patchbay will be not available.
ALSA lib seq_hw.c:457:(snd_seq_hw_open) open /dev/snd/seq failed: Permission denied
Cannot connect to server socket err = No such file or directory
Cannot connect to server socket
jack server is not running or cannot be started

what do I need to do to make it run? I want to hook my keyboard up for recording...
