The Docking station as well as the Notebook has just one Stereo/Mic Combo Audio Jack. I've tried various Headset with 4-Pole and 3-pole plugs. They all work fine on the Notebook but not with the Docking station (40A20090EU). However the Laptop speakers mute as soon as I plug the Headset in the Docking Station so it seems that the driver is somehow aware of it!

I already tried that no success. Without the index parameter alsa switches to the HDMI output by default.

I guess so since there is only one plug. Again all works well when I use the Notebooks 3.5mm plug.

Well here I have another problem. The script doesn't get very far:
ALSA Information Script v 0.4.62
This script visits the following commands/files to collect diagnostic
information about your ALSA installation and sound related hardware.
See 'alsa-info.sh --help' for command line options.
cat: /proc/asound/modules: No such file or directory
Strange thing, /proc/asound exists:
HDMI PCH card0 card1 cards devices pcm timers version
I've compiled the drivers als modules and they are loaded!
