Just saw the release notice for UbuntuStudio 19.04 and it included the
backports of the updated Ubuntu Studio Controls.
So I figured I'd give it a try.
And...it seems to have no difficulty starting/stopping at will. So,
obviously it knows something I don't (which is no surprise. ;) )

Hi,
I have a system running UbuntuStudio 18.04 and I use ffado with jack for
my
firewire AF12.
When I boot the system and start things up with Qjackctl all is good.
(Qjackctl runs a script that starts Calf plugins, zita-lrx, some meters,
and connects up a variety of things the the ins/outs that ffado presents.
Most notably the output of zita-lrx forming a tri-amp system. The input
to
zita-lrx coming from the Calf plugins. )
All works fine, as long as I have no occasion to hit the stop button in
Qjackctl. It runs another script that shuts down Calf, zita-lrx, and
meters.
But, if I attempt to start things again, it says it can't start.
If I kill the ffado-dbus-server, then start ffado mixer (this apparently
starts the ffado-dbus-server), then open Qjackctl again it's already
running. At this point, if I run the script mentioned above, all is good
again.
Does this imply that I'm not shutting down correctly and leaving ffado in
some zombie state?
Is there a proper shutdown that won't cause this?
