I'm curious why you want to switch. The only practicle
reason I can think of is that your hardware runs at
48000 and a conversion has to take place on the fly so
you're trying to improve computational effiency.

You've already got libsndfile installed which includes
sndfile-resample. I'm not sure if you can convert the
rates, start jack at the new rate and open the Ardour
session without having Ardour complain. In theory it
makes sense that you can because Ardour shouldn't care
about samplerate. It should look at jackd for the
currently running rate and examine the files to see
what rate they are. If they are the same, open session
and run. I guess you'll need to test that.
