Hi, all. I have a script which mute the sound when I press. This is the script I use
mute_btn.addEventListener("click",muteVideo);
function muteVideo(me:MouseEvent) {
SoundMixer.stopAll();

}

But when I press it, I found the video I load from external source will stop playing.
This is the way I import my video

var my_nc:NetConnection =new NetConnection();
my_nc.connect(null);
var my_ns=new NetStream(my_nc);
my_video.attachNetStream(my_ns);
my_ns.play("overall.flv");

How come stop sound will cause the video stop playing?
