Udevadm gives no reaction on plugging the headphones, when this line is
active. Deactivation this line, udevadm monitor gives the correct
reaction...

I just downgraded to PA 7.1-2~bpo8+1, and now it works again as before
upgrade to 8.0.1.
So yes, it IS supported.

MPD is talking only to pulseaudio. Two pulse-daemons are running at the
same time (even 3...) One from the logged in user, one from mpd and one
from gdm3.

When every pulseaudio-daemon talkes to the dmix-device, i can hear every
output at the same time. That's what i want.
