Xbox One: background music come on 2 August, video demonstration
But how will it work? Amateur developer in the following video shows us that, with the ability to transform your Xbox in a Developer console , has created a simple music player that takes advantage of this feature.
As you can see, once you start a song you can then leave the app to switch to other tasks without the music stops; more interesting though is that we are shown per minute 1:49, with the "guide" who added on the top is the controls to pause or to pass to subsequent songs and to adjust the volume of the audio playing in the background, if you do not want to say that it is too opaque than the game sound effects.
For now we don't know how many and which apps will support this functionality since 2 August: we will update when we know more. We leave you now to video, enjoy!
