Perhaps you should run claudia on boot? Once you decide to use jack, it should be part of the environment - always there.
If you use $HOME/.jackdrc jack will start with your user session. if you make a file /etc/jackdrc it will be the default jack session parameters for the computer. A clean Ubuntu-Studio install does not have these files. I think .jackdrc gets generated when you run qjackctl for the first time. I think claudia reads and writes ~/.jackdrc. There is a discussion about jackd vs jackdbus at http://jack-audio.10948.n7.nabble.com/more-jack-qjackctl-madness-td8914i20.html Which I have not yet figured out.
