Bug Description
I plug in HDMI through a mini DP adapter. Thus I should see internal speakers and HDMI outputs in Gnome control center but I can only see internal speakers. It's clearly a kernel issue since switching back to 3.19.0-16 solves this bug. I did no kernel tweaks. TLP is installed though.
