How to mute/unmute mic in webrtc

问题

I have read from here that how i can mute/unmute mic for a localstream in webrtc:WebRTC Tips & Tricks

When i start my localstream mic is enable at that time by default so when i set audioTracks[0].enabled=false it muted a mic in my local stream but when i set it back true it enable to unmute. Here is my code mute/unmute for a localstream:

 getLocalStream(function (stream,enable) {
        if (stream) {
            for (var i = 0; i < stream.getTracks().length; i++) {
                var track = stream.getAudioTracks()[0];
                if (track)
                    track.enabled = enable;
                //track.stop();
            }
        }
    });

Can someone suggest me how i can unmute mic back in a localstream.

I assume that your method getLocalStream is actually calling navigator.getUserMedia. In this case when you do this you'll get another stream, not the original one. Using the orignal stream you should do

mediaStream.getAudioTracks()[0].enabled = true; // or false to mute it.

Ahhh there is a good way to do this:

mediaStream.getVideoTracks()[0].enabled = !(mediaStream.getVideoTracks()[0].enabled);

There are 2 properties enabled and muted. enabled is for setting, and muted is read-only on the remote side (the other person) (I have tried, setting muted does not work, basically, value cannot be changed)

stream.getAudioTracks()[0].enabled = true; // remote one will get muted change
