Re: [Jack-Devel] Jack won't start on boot

The content of /etc/security/limits.conf or /etc/security/limits.d/audio.conf are important, too. The output of the command id shows, if the user is added to the real-time/audio group that should be mentioned by /etc/security/limits.conf or /etc/security/limits.d/audio.conf . When installing jack on Ubuntu, a dialoge should have ask you to set up limits... as well as adding the user to the real-time/audio group.
