Have you tried running something like this:
ecasound -f:16,2,44100 -i track.wav -o alsa
Have you also experimented with card and subdevice numbers and
alsaplugin?
ecasound -f:16,2,44100 -i track.wav -o alsaplugin,1,0
You can fiind the right card number looking at:
/proc/asound/cards
Also, when you use the microphone as an input, this would be mono, so
something like:
... -a:2 -f:16,1,44100 -i alsaplugin,1,0 -f:16,2,44100 -chcopy:1,2 -o
output.wav
If you want a stereo file.

HTH.

Best wishes,

Jeanette
