Thanks for the hint with pavucontrol.
Unfortunateley, pavucontrol shows in the profile selection menue the
HDMI Output always as "unplugged":
"Digital Stereo (HDMI) Output (unplugged)"
And also the corresponding output device:
"HDMI / DisplayPort (unplugged)"
Also the sink list shows the device as "available: no". I gues that is
the problem. How could I get the HDMI Output recognized as "plugged
in", what it really is? (With Ubuntu 14.10 it works)
pacmd list-sinks
1 sink(s) available.
