have you got qjackctl's "interface" set to "hw:0,0", "input device" set
to "hw:0,2", and the "output device" set to "hw:0,3"? this should give
you 16 input and 16 output channels (you might have to set them in
qjackctl, too). you don't neet to run it through the jack51 interface,
as this will give you multi-channel playback by default ...
