That didn't work, but thanks. It seems strange that this is so difficult. When using ecasound in interactive mode I've been adding outputs with this command:
ao-add jack_alsa
But how can I tell ecasound that the curently selected channel needs to be connected to alsa_pcm:playback_3 or playback_4 ?? It always just defaults to connecting to playback_1 and playback_2
It should be noted that i will eventually need all 4 channels going at once, so copying from one channel and then muting won't work.
Any help is appreciated.

My setup works great for multi-track recoding with Ardour plus tons of other audio hi-jinx. Now I am working with ecasound and I need to know how to play a mono wav file out any of the 4 outputs on the Delta-66. What command would I use to, say, play sine.wav on the 3rd hardware output?

there are some examples in this document:
http://eca.cx/ecasound/Documentation/examples.html
ecasound -i sine.wave -erc:1,3 -eac:0,1 -o alsahw,0,0
(* copy the signal from sine.wav, channel 1, to channel 3.
Then mute channel 1, i.e. amplify channel 1 by factor 0. *)
This routing can also be done in Jack.
Hope this helps (not tested)
