Updated on 10-29-2018 to replace getAudioTracks with getTracks:

var canvasStream = canvas2d.captureStream(25); // parameter is optional

// get first audio track
// var audioTrack = audioStream.getAudioTracks()[0];
var audioTrack = audioStream.getTracks().filter(function(track) {
    return track.kind === 'audio'
})[0];

// append audio track into Canvas2D stream
canvasStream.addTrack( audioTrack );

// now canvas2D stream has both audio and video tracks
// peerConnection.addStream( canvasStream );
canvasStream.getTracks().forEach(function(track) {
   peerConnection.Track( track, canvasStream );
});

// create offer or answer descriptions
peerConnection.createOffer(hints).then(success).catch(failure);
