  I've had to use the jack_connect command outside of ecasound to effect some routing.
  You can use -o jack_generic,out_name to identify your output channel then
  jack_connect out_name:out_name_1 alsa_pcm:playback_3
  jack_connect out_name{out_name_2 alsa_pcm:playback_4

  or something like that.

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?
