Description

Sound in firefox works just fine, with or without headset.
But in chrome, there's significant echo when sound plays on speakers, effectively forcing users to use headset.
This is most likely due to how MediaStreams.attachAudioStream() sets up mixer:

      var ctx = voice._inputAudioNode.context;
      var gainNode = voice.getSoundGain();
      voice._streamingSource.connect(voice._soundPanner);
      voice._soundPanner.connect(gainNode);
      gainNode.connect(ctx.destination);      

That's a dirty hack for possible babylon and/or chrome bug that may or may not be there: https://forum.babylonjs.com/t/sound-created-with-a-remote-webrtc-stream-track-does-not-seem-to-work/7047
