Jack is a daemon that provides connection services between various applications.
If you have Ubuntu Studio installed, in the menus look for "Jack
Control". After that all you need to do is hit the start button. If
everything goes well, its display will say "Started". After that you
can use Jack-supporting software. You can create connections between
various applications (rerouting inputs and outputs) with the "Connect"

There is also a very helpful, generic mailing group called Linux Audio
Users in, I would recommend subscribing to that
mailing group since quite a lot of linux and audio creation questions
and answers happen there.
