To add to your response below...

What I don't understand is why this process is not already an automated 
feature in the pulse applets? Was it a case of not enough time or was it 
purposefully left out of the mix?

FWIW, I am running qjackctl and stopping pulse from the config cmd line 
settings. Once qjackctl has started jack it then allows pulse to 
connect. However I still have a problem with pulse not actually knowing 
that it has got jack inputs for other apps to access. It knows that it 
has jack outputs so why not the jack inputs?  qjackctl tells me that I 
have two pulse ins and two pulse outs so I consider that a pulse bug or 
config issue. Either way why do I even have to think about this?

Pulse can be made to work seamlessly with jack so why not add that 
feature to the automated toolset?
