I have my Surface Book connected to an external monitor through the surface dock. My PC speakers are connected through the monitor's USB hub rather than the surface dock. I am trying to find a power plan setting that turns of the display after (x) mins of inactivity, while music from Spotify/iTunes keeps playing. As soon as my monitor turns off, the music stops shortly after, though the computer is not set to sleep. Some other PC manufacturers with custom settings for power management have a feature to allow media to keep playing when the display is turned off. It was never an issue on my MB Pro either. Any suggestions on the SB?
