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.
