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";
