When using Jack, I find easier to launch jack from a jack
control
app (I use Qjackctl), start csound with -+rtaudio=jack and
then
make the connections using the QJackctl patchbay.

I could not find a way of connecting csound directly to alsa
hardware
input/output (or any other jack client)  from the csound
command-line. The
command help does not mention an option to do this. Is there
one ?

For using only Csound and Jack to recursively process (so having 
several Csound processes being processed by other Csound processes) it 
seems necessary to include also the -+jack_client= flag so that 
you can multiply instantiate Csound and not have errors when you try to 
initialize two Jack clients with the same (default) name.

As far as connecting a Csound process to a specific Jack port or 
process via the Csound commandline, I am not sure of a way to do this. 
It seems like Qjackctl/jackd like to decide where routing happens and 
to what.

I am also interested in comments on how to set Csound's Jack output 
destination via the commandline but am not aware of a way to do so at 
present; possibly is there some numeric arg to the -o flag ?
