Stopping all sounds on a timeline?

programming flash

Is it possible to stop all sounds that are currently playing in a movie and at the same time stop future sounds that the playhead will encounter on the timeline?

Here is the code I’m using on the ‘mute’ button now:
[AS]
mute_mc.onPress = function() {
this._visible = false;
stopAllSounds();
//fadeout();
};
[/AS]
