streams with audiotracks only are not recorded and give any data on ondataavailable event

[vishnusadanandan]

I am creating a stream object from MediaStream API. and also I add an audio track to this stream. when i recorded it using MediaStreamRecorder i did not get any data on ondataavailable. But when i add both audio track and video track it works well. Please help me to figure this out

const stream = new MediaStream();
const audioTrack =  // get audio tracks from a stream.
stream.addTrack(audioTrack);

const recorder = new MediaStreamRecorder(stream);

recorder.ondataavailable = function(){
 // not even call
}
