There is a group of tools known as jack example clients which may be useful. Actually jack_connect is part of that, look in /usr/bin and see what other jack* files exist, you probably already have them. jack_lsp lists ports jack_wait waits for various jackd events and then exits; see the help file > The reason being is I need to put a sleep into my script to connect the > jack ports: > > /usr/bin/obs & > sleep 10 > jack_connect system:out_1 OBS:jack_in Is jackd already running? jack_wait would be for waiting on jackd to finish initializing in cases where obs quits out right after starting because it cannot detect a jack server running. > I'd like to eliminate the sleep command and poll jack to see if OBS has > any port available. I'm not sure how difficult it would be to parse the output from jack_lsp, but I think it should be possible, and if there are no obs ports when you run the command, sleep 1 or 2 seconds and run again. -- Chris Caudle _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
