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 \

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?
