Public bug reported:
I have a Lenovo P50 with the docking station. When the laptop is plugged
into the docking station sound will not play out the external port.
An lspci -n gives me:
00:1f.3 Audio device [0403]: Intel Corporation Sunrise Point-H HD Audio
[8086:a170] (rev 31)
I have updated the bios.
