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.
