Bug Description
[Impact]
With Ubuntu 16.04, there is no audio (output) interface shows up in Sound settings when connecting an audio capable monitors to the HDMI, mDP and DP ports in Dell WD15 and TB15 docking stations.
Fixed in 4.11-rc1 and up.
[Test case]
Hook up a HDMI/DP monitor, test that audio works.
[Regression potential]
This is a new feature. Regression testing has been conducted on non-MST setups (SKL/KBL which use i915_bpo), where HDMI/DP audio still works. i915 has been tested on BDW and HDMI audio still works.
