<div dir="auto">I use jack-matchmaker which I believe is based on one of the above mentioned or something similar. It can be started before or after and will automatically re/connect any connections and check any newly created ports against the argument's given. You can also just assign one port and it will make all possible connections , or multiple specific connections per pair of arguments if you use regular expressions well</div> <div class="gmail_quote"><div dir="ltr">On Tue, Jan 29, 2019, 02:02 Peter P. <<a href="mailto:peterparker@fastmail.com">peterparker@fastmail.com</a> wrote: </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Paul, Elijah, everyone, thanks for your suggestions! I went with jack_plumbing. Can anyone confirm that jack_plumbing will need to be started before the applications which it is about to manage? It does not manage connections already made? I am on the lookout for a way to start jack, jack_plumbing and a jack-aware application on the command line and restart each of them should they crash/die and restore connections no matter in which sequence the three come up again. It seems jack_plumbing needs to be started after jackd but before applications it is supposed to manage. I am afraid I have to write a script using jack_connect then. For handling of jack connections on headless machines/command line, I am looking for the best way to make connections once an application has been started or restarted. It would be great if applications could generally honor environment variables like $ JACK_PORTS=system:playback_1 mediaplayerapp but I suppose that implementation is up to the application programmers. * Elijah Abdul Rahman <<a href="mailto:elijahjuanye@gmail.com" target="_blank" rel="noreferrer">elijahjuanye@gmail.com</a>> [2019-01-29 06:19]: > An application I've been using is called aj-snapshot.

Thanks Elijah, will look into aj-snapshot in comparison to jack_plumbing as well. cheers, P _______________________________________________ Linux-audio-user mailing list <a href="mailto:Linux-audio-user@lists.linuxaudio.org" target="_blank" rel="noreferrer">Linux-audio-user@lists.linuxaudio.org</a> <a href="https://lists.linuxaudio.org/listinfo/linux-audio-user" rel="noreferrer noreferrer" target="_blank">https://lists.linuxaudio.org/listinfo/linux-audio-user</a> </blockquote></div>
