title: Change sink id of audio track of video element using setSinkId api
body: <p>I am trying to change audio(only) output device of a video element but can't set the sink id for the audio.</p>
  <p>It worked with audio element but while setting sink id on video element didn't work directly therefore I tried by getting <code>audioTracks</code> from video's <code>srcObject</code> stream</p>
  <pre><code>const stream=videoElement.srcObject;
  stream.getAudioTracks().forEach(track=&gt;{
    track.setSinkId(deviceId);
  })
  </code></pre>
