@Stefan - and others,

This is something that needs to be fixed once per type of laptop, so this is essentially one bug per machine. Essentially, for every laptop, we need to add its ID to a table to support the docking station.

Looking at the upstream code, below are the machines currently supported, with ID number and well known name. If you have one of these, and it does not currently work, you can probably make it work by following this procedure: https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS

If it is not listed, please file a new bug (using the "ubuntu-bug alsa-driver" command, as this will automatically attach the relevant ID), then write a comment in this bug with a pointer to the new one. Thanks.
