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?
