MediaSession: setMicrophoneActive() method

The setMicrophoneActive() method of the MediaSession interface is used to indicate to the user agent whether the user's microphone is considered to be currently muted.

Call this method on the navigator object's mediaSession object.

Note that the status of the microphone is not tracked in the MediaSession itself, but must be tracked separately.

active

A boolean indicating whether the microphone is considered muted or not.

None (undefined).

Below is an example of updating the microphone mute state of the current MediaSession, as well as listening to requests to change the mute status with setActionHandler().

let microphoneActive = false;

navigator.mediaSession.setMicrophoneActive(microphoneActive);

navigator.mediaSession.setActionHandler("togglemicrophone", () => {
  microphoneActive = !microphoneActive;
  navigator.mediaSession.setMicrophoneActive(microphoneActive);
});
