miguelao has just created a new issue for 
https://github.com/w3c/mediacapture-fromelement:

== What happens to the audio being rendered to a Media Element when it
 gets captureStream()ed ==
During [Chrome 
implementation](https://codereview.chromium.org/1781043002/) of 
[captureStream()](http://w3c.github.io/mediacapture-fromelement/#html-media-element-media-capture-extensions)
 for <audio> elements or <video> elements with audio active, 
@dalecurtis brought up the question of what is the model for accessing
 the Media Element audio data, i.e. what happens if the media tag is 
playing back a certain audio track, after captureStream() successfully
 returns a MediaStream with (at least) and audio track:
- the audio being played back is routed exclusively to the Track, 
hence the Media Element playback "stops"
- the audio being played back is "copied" to the MediaStream Track.

I understand this might be a question for the Media Element itself, 
@foolip?
