many consumer audio interfaces only run a 48kHz. if JACK is using the
hw:N devices via ALSA (the default) this is the only rate it will ever
run at. you could tell JACK to use plughw:N instead but then you get
nasty ALSA resampling code between JACK and your speakers.

either get a new interface or learn to live with 48kHz or put up with
ALSA's resampling code or reimplement the latter. 4 options to choose
from. freedom! :)
