If you just want to disble the voice from microphone to come into the speakers do

myMic.setLoopBack(false);

This will disable the sound detected by microphone to be played in the speakers.

EDIT1:

//use the function to disable sound completely.


 private function disableSound():void
 {
    var newSoundTransform:SoundTransform=new SoundTransform();
    newSoundTransform.volume=0;
    this.soundTransform=newSoundTransform;
}

Call the above function in init() function. This will completely disable all sounds coming from the application.

Actually when i increase the volume on the system it just reproduces some unwanted noise so trying to get rid of it.. – Rajeev Jan 18 '11 at 09:21
if you want to completely disable sound for your application, then you can simply use a soundTransform object on the application.Ill edit my answer with the required changes shortly. – Neeraj Jan 18 '11 at 09:27
I 2 found a fix but not so sure of it,in the above code itself Mymic.gain *= 0.8; seems like it solved my problem.Is this a valid fix? Also how will i change the bar color in the above code – Rajeev Jan 18 '11 at 09:54
Rajeev, the fix if working seems to be a good way to do it.Also to change the colour use – Neeraj Jan 18 '11 at 09:58
Are you sure about it the flex compiler had given me some error i tried it days ago – Rajeev Jan 18 '11 at 10:02
im sorry to change the colour of the progress bar you need .Please try this out.This will surely work – Neeraj Jan 18 '11 at 10:07
That worked but even the background color changed ?Can we not retain the background color and change only the bar color – Rajeev Jan 18 '11 at 10:12
try using labelPlacement="bottom" , that would actully reduce the size of the progressbar and you would see two seperate colous for the progressbar and the label. – Neeraj Jan 18 '11 at 10:38
And neeraj is there a way to disable the security question that is been asked when the microphone is accessed Allow/Deny.. – Rajeev Jan 18 '11 at 10:43
I checked a few places, it doesnt seem possible, the reason is that, the browser doesn't allow any webapp to directly access low level resources like webcam data, without users permission. – Neeraj Jan 18 '11 at 14:44
Thanks for all the help Neeraj.Appreciate it – Rajeev Jan 18 '11 at 17:43
