AFAIK, in order to render in realtime to Jack you need these options:
-+rtaudio=JACK -o dac:alsa_pcm:playback_

This should force csound to automagically connect to your card's output port.

If you are using Blue, you need to specify it in the Option dialog.
IIRC, after selecting JACK as your driver it will recognize the ports
on its own (providing jack is running when you're setting it up).

However, you may need to tweak the buffersize and whatnot, I've had
issues with that in the past but cannot recall the details.  another
anomaly I have encountered is that when I start jack server from
qjackctl, csound crashes it.  Otherwise, if you start jack server from
the command line it works fine.  Beats me.   I have not yet written
about it to any m-l because it is unclear to me where should it go.

Anyways, HTH.
