If using jack I recommend mhWaveEdit, the gui is not as nice, but jack 
works right. It is interesting, that in talking to devs in Audacity, they 
will answer about anything, but the idea of jack being open from 
application start gets ignored... not a no we won't do that or it's too 
hard, just silence. There is a note on one of their pages that says "we 
welcome feedback on jack implementation" but it is really bogus. The 
recording part of the app is not properly designed for any audio back 
end... pulse, windows, OSx, whatever. I think one needs to realize 
audacity, despite all that has been said, does not do jack. Record 
somewhere else, then use it to edit.

This is one of those cases where Audacity->pulse->jack and 
jack->pulse->Audacity is what works best. Really, this is meant to be 
stand alone and connect direct to ALSA.

In my talking with the devs, I would agree.
