pactl to control Pulseaudio from scripts (from package pulseaudio-utils).Qjackctl (from package pulseaudio-utils).jack_control (from package ack-audio-connection-kit-dbus).Qjackctl after Shutdown script re-activates the audio card in Pulseaudio: pactl suspend-sink alsa_output.pci-0000_00_1b.0.analog-stereo 1.

the default sink in Pulse audio is switched to audio card because jack-out disappears.jack-source and jack-sink are removed from Pulseaudio automatically by d-bus.Jackd stopped by Qjackctl over dbus - 'Enable D-bus interface' option.If 'Stop JACK audio server on application exit' is not checked, I can close Qjackctl and rerun it without disturbing the setup.Īfter stopping Jack by Qjackctl, everything returns to plain uncluttered Pulse! (I skip hardware input suspend, because I don't use it anyway) So the system is reconfigured to use 'Pulse on top of Jack'. Qjackctl after the startup script changes the default sink in Pulse to jack_out: pactl set-default-sink jack_out (at first it looks unnecessary, as all running PA clients are switched to the new sink, but new apps will get stuck on the suspended sink without this command).Pulse automatically detects jack start over D-Bus and loads jack sink and jack source.Jack is started over d-bus: jack_control start.The Qjackctl startup script suspends the primary audio card in Pulseaudio and allows Jack to get access to it: pactl suspend-sink alsa_output.pci-0000_00_1b.0.analog-stereo 1.Now on boot the PC runs with PulseAudio only, everything automatically works as without Jack. 'Enable D-Bus interface' is important for Qjackctl itself.
