[LAU] Ecasound mono wave file and autostart

Hi all, In need of a (console) wave file player which is also jack-transport aware, serching around I came up with this ecasound command: ecasound -c -i ultimo_sole_audio_dial_eff.wav -o jack,system \ -G:jack,ecasound,recv However I have two problems: 1. The above starts in interactive mode while I'd like ecasound to autostart when run. It seems that omitting -c will cause ecasound to exit upon jack transport stop, which is a no-go for me 2. The wave file is mono: I tried various combinations sucj as jack_multi but this will always either create two outputs or one output and connect it only to one of the system (stereo) outputs. I guess I could work-around problem 2 by either converting the file to stereo or further using jack_lsp in my script to connect the output to the second system port.. Any idea about 1? Lorenzo
