This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The playbackState property of the MediaSession interface indicates whether the current media session is playing.


var playbackState = MediaSession.playbackState
MediaSession.playbackState = playbackState


One of "none", "paused", or "playing".


The following example sets up event handlers, for pausing and playing:

var audio = document.querrySelect("#player");
audio.src = "song.mp3";

navigator.mediaSession.setActionHandler('play', play);
navigator.mediaSession.setActionHandler('pause', pause);

function play() {;
   navigator.mediaSession.playbackState = "playing";

function pause() {
   navigator.mediaSession.playbackState = "Paused";
