I'm pretty new to this also and am trying different things. We have 
different programs and setups. But make sure you install "Jack Example 
Clients". They are command line programs for doing all kinds of useful 
things (and sometimes the only way).

I know on my CCRMA 7 system, I do...
yum install jack-audio-connection-kit-example-clients

If that doesn't work, do...
yum list jack*

Once installed... try (in a shell)...
(list jack ports)
(connect ports)

Make sure you use the --help switch to see the options
(jack_programName --help)

I found...
jack_lsp --aliases
jack_lsp --properties
...to be very helpful, but there's more.

I found it almost impossible to get any info about jack related 
programs. But if you do (in a shell)...
(press tab twice)
You'll see the programs that come with "Jack Example Clients".

Let me know how this works out. I'm learning also and would like to know 
what you discovered...
