What jack_control does inside I am not sure. I am sure changing the device 
or SR effectively restarts jack as you say. I have not played with SR but 
changing latency makes some software go odd already. rakarrack comes to 
mind. My work station runs at 48000 for everything. The analog part of my 
audio interface seems to sound best there.

The thing is, what the original poster is really asking is not 
that clear to me.
