Have you tried starting jackd from the command line instead of using
qjackctl? The -r44100 option should do it. Don't forget to tell it which
device you're using eg. -d hw:0, because recent versions of alsa use
a plugin as default device (instead of hw:0 as previously) along with
software rate conversion (which you definitely don't want here).

It might be worth checking what command qjackctl is sending to jackd
to make sure the right device is being specified.
