Chris, thank you very much for your answer. The situation is the following. As a normal user I want to use qjackctl in order to start jack. Then I get the followin message:
cannot lock down memory for jackd (Operation not permitted) loading driver .. apparent rate = 48000 creating alsa driver ... hw:0|hw:0|1024|2|48000|0|0|nomon|swmeter|-| 32bit control device hw:0 configuring for 48000Hz, period = 1024 frames, buffer = 2 periods Couldn't open hw:0 for 32bit samples trying 24bit instead Couldn't open hw:0 for 24bit samples trying 16bit instead Couldn't open hw:0 for 32bit samples trying 24bit instead Couldn't open hw:0 for 24bit samples trying 16bit instead JACK: unable to mlock() port buffers: Operation not permitted jack_create_thread: error 1 setting scheduler parameters after thread creation: Operation not permitted cannot start watchdog thread cannot load driver module alsa 09:57:47.539 JACK was stopped successfully. 09:57:49.523 Could not connect to JACK server as client. Only when I run the command as root I can start jack. As you suggested, the problem has to do with realtime privileges. It seems that the answer of John O'Hagan provides the solution, which requires a kernel recompilation.
