Need to setSound at lowest possible volume to minimize intrusiveness

The swf I need to modify from the commonsense approach is below. Because this ad expands when a 120x90 “trigger” is rolled over the client has asked for the ad to start on rollover which I have accomplished with a button on frame 1 with a on (rollover) {
gotoAndPlay(2);
}

Because people will accidentally rollover this ad and start it playing the client wants the ad to start at a 0 volume level. This way the accidental rollovers can still choose to turn up the volume to hear the commercial if they so choose.

I have tried changing the sound level in the AS in a couple places but neither worked. In addition intuitively the slider also needs to be in the 0 position and I have a feeling just moving the graphic instance of the volume button is not the way to go.

actionscript for volume control is:

onClipEvent (load) {
_root.volumeLevel = 100;
left = _x-50;
right = _x;
top = _y;
bottom = _y;
}
onClipEvent (enterFrame) {
if (dragging) {
_root.volumeAmount = ((_x-left)*2);
_root.volumeLevel = Math.round(_root.volumeAmount);
_root.mySound.setVolume ((_x-left)*2);
if (_root.volumeLevel > 1){
_root.offonText = “sound on”;
}
else if (_root.volumeLevel < 1){
_root.offonText = “sound off”;
}
}

}

actionscript for movie is:

framerate = 25;// change the framerate to match the video
// volume controls
mySound = new Sound();
mySound.attachSound("");
mySoundsetVolume(0);
mySound.start(0, 999);
//
this.pausebutton._visible = 0;
this.playbutton._visible = 1;
timing = true;
milli = 99;
//
playbutton.onRelease=function() {
unpause();
pausebutton._visible = 1;
playbutton._visible = 0;
};
//
pausebutton.onRelease=function() {
pause();
playbutton._visible = 1;
pausebutton._visible = 0;
};
// timer script – total frames divided by the frame rate
_root.onEnterFrame = function() {
howmanyframes = _totalframes;
whichframe = _currentframe;
totalTime = getTimer()/1000-pauseLength;
goTime = totalTime-buttonPressTime;
//
if (timing) {
mins = Math.floor((howmanyframes-whichframe)/(framerate60));
secs = Math.floor(((howmanyframes-whichframe)/framerate)-(mins
60));
milli = Math.round(milli) - 1;
if (secs<10) {
secs = “0”+secs;
}
if (mins<10) {
mins = “0”+mins;
}
if (milli<10) {
milli = “0”+milli;
}
if (milli == 00) {
milli = 99;
}
}
};
//
function restartTimer() {
mins = “–”;
secs = “–”;
milli = “–”;
buttonPressTime = getTimer()/1000-pauseLength;
pause();
};
//
function pause() {
pauseTime = getTimer()/1000;
timing = false;
this.stop();
};
//
function unpause() {
unpauseTime = getTimer()/1000;
pauseLength = (unpauseTime-pauseTime)+pauseLength;
timing = true;
this.play();
};
//
stop();
