<br>
Once you decide to use jack, it should be part of the environment -<br>
always there.<br>
<br>
If you use $HOME/.jackdrc jack will start with your user session.<br>
if you make a file /etc/jackdrc it will be the default jack session<br>
parameters for the computer.<br>
A clean Ubuntu-Studio install does not have these files. I think<br>
.jackdrc gets generated when you run qjackctl for the first time. I<br>
think claudia reads and writes ~/.jackdrc.<br>
<br>
There is a discussion about jackd vs jackdbus at<br>

<br>
Which I have not yet figured out.<br>
