How to remove music added to the frame

Question

I have added music (in loop) to the first frame of main timeline (through property panel), So it keeps playing till the last frame, but when the control jumps to first frame again after finishing all frames there are two musics playing, How can that be stopped?

Answer 1

You don't have a lot of control if you dragged the sound to the stage and then set it to loop in the properties panel. You can either jump back to frame 2, so you don't play the sound at frame 1 when you loop the timeline or you can control the sound yourself using AS. Here's a little sample you could place in frame 1 that loops the sound 'libSound' 999 times, and only plays one time by using a flag variable:
var a:Sound;
var c:SoundChannel;
var isPlaying:Boolean;
if(!isPlaying){
    isPlaying = true;
    playSound();
function playSound()
    a = new libSound(); //sound from library
    c = new SoundChannel();
    c = a.play(0,999);
