Can't get jack running with alsa

Hii, I want to try out sonic pi, which requires jack to run.
But when I try "jack_control start" i get that error message:

 DBus exception: org.jackaudio.Error.Generic: Failed to open server

here is my output of ~/.log/jack/jackdbus.log:

Re: Can't get jack running with alsa

Have you also installed the realtime-privileges package and added yourself to the appropriate group as directed by wiki?

https://wiki.archlinux.org/index.php/JA … stallation

I'd also look closely at the playing nice with alsa section in the wiki.

Yes, I tried everything from the wiki, but it didn't work.
