      I am not sure what you mean by this. It is possible to make changes
      to jacks sample rate if you use jackdbus from jack2, but still only
      one rate at a time. Jack will not change rate depending on the rate
      of a sound file. That doesn't make sense (but then neither does
      96000).


This is incorrect. There is no API to change the SR of a running JACK instance.
 
You can, of course, stop and restart JACK with a new SR, but that's not really
what is being requested.

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.
