invalid volume values

On the safari webrtc , when we clone the audio stream and try to apply the mute state then mute state is not getting applied. 

Steps -
-----------------

1.Have a audio muted stream 

2.Clone that audio stream 

3.Then apply unmute on this audio stream 


Observed -
------------------

When we un-mute we observe the invalid volume values for the volume.


Please find the screen shot attached.

Thanks for reporting this bug.
I was not able to fully reproduce that bug.
Using https://webrtc.github.io/samples/src/content/getusermedia/audio/ and trying to play with track cloning and the enabled attribute, everything seems to work as expected.
The only thing that is different is trying to do something like:

var track = stream.getAudioTracks()[0];
track.enabled = false;
var clonedTrack = track.clone();
clonedTrack.enabled = true;
audio.srcObject = new MediaStream([clonedTrack]);
// There audio is not playing
audio.pause();
audio.play()
// There audio is playing

Kishor, is that your issue? Can you precise what you cannot do here?
A reduced script/example showing your issue would be great.
