Hello, On headless embedded computer with Debian I mostly start jackd (jack2) with dbus session::
dbus-run-session jackd -a a -d alsa ... since I prefer using the debian packages before compiling on those slow devices. 'man dbus-launch' says: [...] To start a D-Bus session within a text-mode session, do not use dbus-launch. Instead, see dbus-run-session(1). [...] I put this in a systemd run script with all the ambidecoder and so on stuff I need connected. Any objections to this approach, since I am not really a systemd or dbus guru, just got it from man pages. mfg winfried Am Dienstag, 14.
