I am on Ubuntu 16.04.1 using Gnome as my DE and WM. With the gnome tweak tool, I have made it so that when my laptop lid is closed with an external display, nothing happens. When I close my laptop lid, there is no audio output at all. I suspect it is something to do with pulse audio. Can anyone help me?
Edit: There is no audio output from any source(speakers or headphones). I am quite new to ubuntu, so please do tell me how to give you my sound settings. I was just speculating that it might have been a pulseaudio issue. With gnome-tweak-tool, i went under the "power" section and enabled "do nothing" when laptop lid is close and power is plugged in.
