This command plays back the first track, but records a blank, empty wav file:
ecasound -f:f32_le,2,48000 -c -a:1 -i echomadness.wav -o jack_auto -a:2 -i
jack,fretless:left -o fretless.wav -G:jack,recorder,sendrecv -z:multitrack
What might I be doing wrong here?
It used to work, but doesn't anymore, and I can't think of anything I might have
changed recently on this system.
