Ok, speaking of which, apparently I need to use jackd2

JACK server starting in realtime mode with priority 10
self-connect-mode is "Don't restrict self connect requests"
Failed to connect to session bus for device reservation /usr/bin/dbus-launch terminated
abnormally with the following error: Autolaunch error: X11 initialization failed.
Audio device hw:0 cannot be acquired...
Cannot initialize driver
JackServer::Open failed with -1
Failed to open server

There are many, here an incomplete selection:
1. use jack1
2. recompile jack2 without dbus support
3. hack around it [1]
4. use a dummy virtual X
