Hi all.
I'm running jackd1 (0.125.0) on debian 9 (stretch) and its
"auto-starting" facility works perfectly whenever I use jack-play. I
now want to use pulseaudio-module-jack, but "pactl load-module
module-jack-sink channels=2" fails (the command returns "Failure:
Module initialization failed" and I see "jack_client_open() failed" in
the journal).
Is this a bug, or is it "intended/expected behaviour"? (I don't
understand how jack-play starts jackd1. Is it dbus magic, or something
else?)
Many thanks, Jaime

I am not positive I remember the details correctly, but I believe the auto
start behavior is a function of the application, not the jackd server.

Perhaps pulse expects jackd to be running when the module loads. You may
have to start jackd manually, or switch to jackd v 2.

Something else, jackd v2 has dbus support, jackd v1 does not. I believe
that applications are supposed to check ~/.jackdrc to determined the
desired default command line for the non-dbus version, I'm not sure how an
application would determine if the dbus version was available. I guess it
could try starting the dbus version first, and if that did not work look
for a .jackdrc command, and if that was not available start jackd and
accept the default behavior.
