 From that issue thread I see it's only in 240 - so this is not the
 problem I suppose.
  
For your case you'd start jack with a user that has necessary
permissions, eventually in a screen or tmux session.
Same with the capture script, and this one can wait until jack is
available:
jack_wait -w
#... do capture etc.
