Loading FLV with no sound

HI,

I am streaming an flv through the following code:

//load/play flv

var connection_nc:NetConnection = new NetConnection();
connection_nc.connect(null);
var stream_ns:NetStream = new NetStream(connection_nc);
vidTV.attachVideo(stream_ns);
stream_ns.play(“video.flv”);
//

the flv starts playing with sound when it loads…how could I load it without sound and then have a mute/sound on button to turn on and off the sound?

I’ve tried making a movieclip, a button and added some more actionscript and doesn’t work:

//sound object movieclip actionscript

this.createEmptyMovieClip(“vSound”,this.getNextHighestDepth());
this.vSound.attachAudio(ns);
var so:Sound = new Sound(vSound);
so.setVolume(30);

// button actionscript

butMute.onRelease=function()
{
if(so.getVolume()==0){
so.setVolume(90);
}else{
so.setVolume(0);
}
}

Thank you for the help

charles,
