Ok, I overrided the pin 0x0f to:
-Connectivity: jack
-Device: headphones
and now it shows the ports "Speakers" and "Headphones" as it should.
It correctly switches from "Speakers" to "Headphones" when I plug the
jack, but the sound comes still from the speakers.
I have to mess with the alsamixer's switches to get the correct output
device, as I did before.

What is the meaning of "Channel group" and "Channel (in group)" controls
of in hdajackretask? I can't find any documentation.
The speakers are on channel group 15, channel in group "Front".
The headphones got as default value channel group 3, channel in group
"Channel 30 & 31".
