its reported by the ALSA driver, which in turn is written based on
information available about the h/w. its debatable what ALSA should
report in these situations, but its a driver-level issue, and not
something in JACK's domain.
JACK does NOT resample audio, ever. neither does ALSA if you use the
hw:N device(s).
