I have the exact same issue, Rene.  So far not much progress has been made - unfortunately I'm an ALSA user, not an ALSA developer.  I did create a bug here:

https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3725 (that's bug ID 0003725)

I suspect the issue boils down to the driver not recognizing the way things are "wired" together.  See the bug report for more details about what I've done thus far, which is essentially collection of as much information as possible for the ALSA developers to use in troubleshooting the issue.
