Hi,
Well, in this example, you appear to be trying to play a file on channel1
while recording from /dev/dsp and sending that to duet.wav. If you want
to merge something with stuff from /dev/dsp, you might try:
ecasound -a:1 -i track1.wav -o /dev/dsp1 -a:2 -i /dev/dsp -o track2.wav
If then you wish to play both together,
ecasound -a:1 -i track1.wav -a:2 -i track2.wav -a:all -o /dev/dsp
