@Zisu, that is indeed an unfortunate behaviour of HDMI. I use GMPC to play music, which has a full-screen mode. There's a fullscreen plugin for Rhythmbox. Various other players do too. I sympathise if your favourite does not.

I agree that Caffeine 2.7's functionality should be part of every desktop environment; I'm working towards that!
