如何在android web浏览器上通过agora使用通话声音而不是媒体声音？

<script src="https://cdn.agora.io/sdk/release/AgoraRTCSDK-3.6.5.js"></script>

var client = AgoraRTC.createClient({ mode: 'rtc', codec: 'vp8' });

client.join(appId, channel, token, uid);

client.setAudioProfile('speech_low_quality');

client.enableAudio();

<audio id="audio-player"></audio>

client.on('stream-added', function (evt) {
  var stream = evt.stream;
  client.subscribe(stream, function (err) {
    console.log('Subscribe stream failed', err);
  });
});

client.on('stream-subscribed', function (evt) {
  var stream = evt.stream;
  var audioPlayer = document.getElementById('audio-player');
  stream.play(audioPlayer);
});
