Everywhere you find "card 0" or "hw:0" you need to replace this with
"card 2" or "hw:2". Do not touch the "device 0" stuff, though.

For example: 
$ jackstart/jackd -r 48000 -d alsa -d quattro

Replace "quattro" with the setup you want to use, e.g. "q4" or "q4b",
and "48000" with other samplerates, if you want to use higher rates.
Do not use 44100!
