GetMicrophone from TV Tuner

Question

Hi, I have a TV Tuner attached to my computer, when I do
getCamera, no problem, I get the video from my TV. But, when I do
get getMicrophone, nothing happens, although when I try to use
another app I can hear the audio. What am I doing wrong? Here is
the code:
stage.scaleMode = StageScaleMode.NO_SCALE;
stage.align = StageAlign.TOP_LEFT;
var camera:Camera = Camera.getCamera();
if (camera != null) {
camera.addEventListener(ActivityEvent.ACTIVITY,
function(evt:Event){
trace(evt);
var video:Video = new Video(camera.width * 2, camera.height
* 2);
video.attachCamera(camera);
addChild(video);
} else {
trace("You need a camera.");
var mic:Microphone = Microphone.getMicrophone();
Security.showSettings("2");
mic.setLoopBack(true);
if (mic != null) {
mic.setUseEchoSuppression(true);
mic.addEventListener(ActivityEvent.ACTIVITY,
function(evt:Event){});
mic.addEventListener(StatusEvent.STATUS,
function(evt:Event){});
}

Answer 1

To elaborate a bit more, My Tv Tuner shows up as Camera, but
it does not show up as a microphone, of course, because it's not a
microphone. But the video the TV Turner is providing flash has
audio with it. So, I am wondering if there is a technique to get
GetCamera take the sound as well instead of needing getMicrophone,
since the stream that comes from TV Tuner has audio with it.
Thanks in advance.
