** Description changed:

  I have a Thinkpad T450s. The sound works normally unless it is plugged
  in to the docking station (a ThinkPad Ultra Dock). In that case the
- internal speakers get disabled correctly, but the output of the docking
- station does not work. Speakers which are plugged in directly on the
- Laptop still work.

Title:
  No sound on ThinkPad docking station

Status in linux package in Ubuntu:
  New

Bug description:
  I have a Thinkpad T450s. The sound works normally unless it is plugged
  in to the docking station (a ThinkPad Ultra Dock). If speakers are
  plugged in to the dock, the internal speakers get disabled correctly,
  but the output of the docking station does not work. Speakers which
  are plugged in directly on the Laptop still work.
