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. -ken _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
