Title: No sound on ThinkPad docking station Status in linux package in Ubuntu: Incomplete 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.
