you probably have a consumer audio interface that only runs at 48kHz.
JACK asks for a sample rate as close to 44.1 as possible; your h/w
doesn't support it, so JACK ends up with 48kHz instead and reports that
back to you.

use "plughw:0" as the device name for JACK if you really must avoid
this; otherwise get used to the fact that your h/w is a 48kHz-only
device and that using it at other rates will cost you one way or
