I've already used guitarix in other distros (Debian, Artix) but now (on Archlinux) I'm having error trying to use it. When I start the program (with jackd already runnig through QJackCtl as I always did and worked) it fails wit this error messages:

[16:17:43] system init *** mlockall failed: [16:17:43] system init

failed to lock memory: Cannot allocate memory [16:17:43] system init failed to lock memory: Cannot allocate memory [16:17:44]

loaded state *** from file /home/fabio/.config/guitarix/gx_head_rc

[16:17:44] Jack init *** The jack sample rate is 48000/sec

[16:17:44] Jack init *** The jack buffer size is 1024/frames ...

[16:17:44] PitchTracker *** error creating realtime thread - tuner

not started

I've already added my user to the audio group and restarted but the error remains.

you say you have used it on other distro, but you didn't tell which one it is this time.

@hfiguiere I've edited and added the distros

Apparently on ArchLinux the user needs to be added to a realtime group.
