In IO.pm, I find there a mapping from routing graph
source/sink types to ::IO::* classes (see below). Objects in
these classes generate the Ecasound chain inputs and
outputs.
If we replace this mapping so that all JACK I/O types and
soundcard I/O types map to ::IO::from_rtnull and
::IO::to_rtnull, I think we will be close to what you want.
The command could be named 'arm_rtnull' and would
be used like 'arm' for a one-time change. Does that
sound like it would meet your needs?
FYI, this the current mapping:
-------------------------------------------------------
our %io_class = qw(
null_in ::IO::from_null
null_out ::IO::to_null
soundcard_in ::IO::from_soundcard
soundcard_out ::IO::to_soundcard
soundcard_device_in ::IO::from_soundcard_device
soundcard_device_out ::IO::to_soundcard_device
wav_in ::IO::from_wav
wav_out ::IO::to_wav
loop_source ::IO::from_loop
loop_sink ::IO::to_loop
jack_manual_in ::IO::from_jack_port
jack_manual_out ::IO::to_jack_port
jack_ports_list_in ::IO::from_jack_port
jack_ports_list_out ::IO::to_jack_port
jack_multi_in ::IO::from_jack_multi
jack_multi_out ::IO::to_jack_multi
jack_client_in ::IO::from_jack_client
jack_client_out ::IO::to_jack_client
);
-------------------------------------------------------

--fake-jack is really only for testing. Nama assumes JACK is running,
and uses an internal list of fake JACK clients to check
that correct routing takes place.
In other words, you don't need it, and it probably won't help you. :-)
