 indeed (-:

I use qjackctl for setting up jack.
but first I use envy24control to set up the hardware monitoring etc.

I set the sample rate I want in qjackctl, and start jack, but it always 
reverts to 48000.

soon as I'm finished the book series i'm busy with I'll get into some 
serious messing with jack and friends (-:  (book 4 of 5, shouldn't take 
long)
