Title: Dell XPS 15 2016 with Ubuntu 16 Sound HDMI issues Status in unity-control-center package in Ubuntu: Confirmed Bug description: This issue is related to sound not working properly on Ubuntu when switching between an external display using HDMI with 4K resolution and the standard laptop display. Issue 1 - Sound only works on laptop when plugged into 4k HDMI display Issue 2 - Sound doesn't work when plugged removed from 4k HDMI display When you plug in a 4k Display that supports sound to the Dell XPS 15 2016 model the sound only works on the laptop. Only when you go to Sound Settings and manually select the HDMI output for sound does the sound start to work on the display itself instead of the laptop. When you unplug the HDMI 4k display the sound doesn't work on the laptop. When you go to the Sound Settings dialog it only shows one output that is selected - if you select the same output thats already selected the sound starts to work again on the laptop.
