Hi,
I'm trying to get receive audio data from a USB software defined radio and
pipe it through jack to alsa out and also to another app dl-fldigi.
It's working (off a fashion) using this hacky script
https://gist.github.com/jrobinson-uk/123daebd8ff58d636ba02da9dfd7f3e1 which
basically
starts the jack server
starts the 3 apps to link (mplayer --> alsa_out --> dl-fldigi)
links mplayer to alsa then also to dl-fldigi
I have 2 questions:
Some of the apps either crash occasionally (dl-fldigi) or their is a case
for restarting them (mplayer), at the moment I have to recreate the
connections each time an app closes. Is it possible to create the
connections first and have them persist, then connect the apps when they are
(re)started?
You could set up the connections once with either qjackctl or
aj-snapshot (command-line app), and have them automatically be
recreated. In qjackctl you would create a patch, and load it.
With aj-snapshot, you would have to run it in daemon mode.
