Mute micro phone run time in actionscript

Question

Is there any API call which mutes the microphone in Action Script.If not please tell me how to mute the microphone in Action Script. I tried with the following ways

microphone = Microphone.getMicrophone();
microphone.setLoopBack(false); and
microphone.setSilenceLevel(100);

they don't make any difference to me.

Answer 1

I just found a post which is saying,if we assign gain to 0 then microphone can be muted like below and its working.

microphone = Microphone.getMicrophone();
microphone.gain=0;

Answer 2

The accepted answer will not work very well. Once you set gain like that, if you would try to set gain again to some other value other then 0 it will set the gain, but the sound will not be recorded anymore. (at least to my experience)

To mute you can do it like this:

stream.attachAudio(null);

and to unmute:

stream.attachAudio(mic);
