I'm using a Dell U2414H monitor with DisplayPort video/audio and a USB 3.0 hub for keyboard/mouse.
When the display turns off after x minutes, from the Brightness & Lock setting, the audio shuts off as well. The USB hub works fine, as my keyboard/mouse are plugged in there and that's how I wake the screen. I've only used Ubuntu 14.04 with this hardware, DisplayPort is new to me.
How can I keep the audio streaming when I afk and my screen turns off? (Monitor power button is still turned on.)
