Hi all,
I am trying to run jackd instance from /etc/rc.local (along with a few other
applications) from a custom made init script.

The system is ubuntustudio and I have setup everything to have elevated
permissions when executing applications from the @audio group.

Are you really wanting to run audio while you are logged out? It would be much easier to add a desktop file to ~/.config/autostart/ Like jackstart.desktop with something like:

[Desktop Entry]
Encoding=UTF-8
Version=0.9.4
Type=Application
Name=AutoJack
Comment=Jackdbus starter
Exec=jack_control start
StartupNotify=false
Terminal=false
Hidden=false


Change the Exec to point to a script if you want to add config options, or use jackd instead of jack_control if you don't care about PA-jack bridging.

This will have jack runnning from login.

If you want to headless operation then have rc.local do it as the user that will run this stuff.
