I recently purchased a ThinkPad T460p and installed Ubuntu 16.04LTS on it.
The docking station I use is the ThinkPad Ultra Dock.
If I hook up my Iiyama XB2888HS Monitor (w/speakers) via an HDMI cable directly to the side port of the laptop, everything works fine.
However, if I hook it up via the docking station, this results in no audio being heard.
Looking at the System Settings > Sound > Output, I see that while the the monitor is hooked up on the side, the HDMI appears in the list, but when using the docking station, I only see the PC Speakers and no HDMI.
Is this a known problem and is there any way to fix it?
Thanks in advance for helping me.
