Yes.

If you use pulse audio as your default sound manager and have a script 
to disable, connect and disconnect from jack when jack is 
started/stopped you can keep pretty much forget about connection issues.*

Check the recent archives for examples of how to setup pulse to work 
with jack. There are several methods.  I currently use a script provided 
by Fernando Lopez-Lezcano from CCRMA and have configured qjactkctl to 
run it at start/stop.


*Apart from on a 64 bit system. Then things can get murky with pulse and 
binary apps like skype, flash, real player etc..
