[DP MST] No audio output through HDMI/DP/mDP ports in Dell WD15 and
TB15 docking stations
Status in linux package in Ubuntu:
Triaged
Status in linux source package in Xenial:
Fix Committed
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.
