Hi, Â I'm coding a small application which use pulseaudio. This application works well when I test it inside my user session (x11, dbus, xfce, etc.) Now I would like to start this application as a deamon with systemd (I wrote a simple foobar.service script according to systemd tutorials). Unfortunately this fails with messages: ... mai 08 17:29:02 systemd[1]: Started FooBar. mai 08 17:29:02 pulseaudio[25472]: [pulseaudio] server-lookup.c: Unable to contact D-Bus: org.freedesktop.DBus.Error.NotSupported: Unable to autolaunch a dbus-daemon without a $DISPLAY for X11 mai 08 17:29:02 systemd[1]: foobar.service: Main process exited, code=exited, status=1/FAILURE mai 08 17:29:02 systemd[1]: foobar.service: Unit entered failed state. mai 08 17:29:02 systemd[1]: foobar.service: Failed with result 'exit-code'. ... If I understand well, the pulseaudio client library doesn't find how to reach the pulseaudio server, isn't it? How to fix this? Shall I start a pulseaudio server dedicated to the foobar user (the one who start my foobar daemon)? Or a "system" pulseaudio server? Best regards Christophe
