This is the code to detect the mic mute. stream.getAudioTracks()[0].muted this code doesn't change the mic to muted state.

Issue:

The Below code doesn't detect the mic mute or unmute/state on the chrome browser on a Chromebook device.

navigator.mediaDevices.getUserMedia({audio: true})
  .then(stream => {
    console.log("MediaStreamTrack muted:", stream.getAudioTracks()[0].muted);
  })
  .catch(err => console.log(err));
