Many built-in/inexpensive sound cards are stuck at 48K. Possibly this
one is also?
It's still a bug for JACK not to report any error.
Does aplay report any errors with a 44100Hz file?
In fact it happens on my laptop (it has a VIA AC97 chip). Jack does
report the sample rate you choose but the other applications connect to
it at 48000Hz.
I guess it is because they're designed to play dvds (which are at
48000Hz) and they don't have a built-in sample rate converter. Maybe
JACK assumes they always have one since it is designed for high end cards?
I think cards defaulted to 48000Hz before DVDs existed. I believe the
AC97 spec requires it and it's cheapest to support a single sample rate
and rely on a software sample rate converter for everything else.

Not all. On my desktop pc (which has a VIA 8237, an AC97 based card -
the mb is a ASUS K8V-X) jack lets me choose both sample rates.

But then both qjackctl and Ardour report 48000 as the samplerate.
All help is appreciated.
