You need to carry out 3 steps to be able to run JACK with RT scheduling.

Add User To Group Linux

I mean, is so simple, just add those lines [email protected] - rtprio [email protected] - memlock unlimited, and obviously add my user to the audio group, in which he already is, but then just added the lines @audio - rtprio 99 @audio - memlock 250000 @audio - nice -10 ...

The ´echo´ command normally just ´echoes´ whatever you type on the keyboard back to standard output, normally your PCs monitor.

All you have to do for this is give your audio group permissions to access the rtprio, nice, and memlock limits.

For this reason, jackd is compiled with RT support disabled by default (but can be enabled at runtime via cli parameter). If a question you asked has been answered, accept the best answer by clicking on the checkbox on the left side of the answer. Now, you have to make sure you are in the audio group, so do a: sudo adduser mao audio supposing that mao is your user name.

The ´>>´ changes that to appending that echo to the end of the two files in /etc/security.

All of these settings should be taken care of automatically. I'm having the same issue as that listed in the bug report.
