How to show a button when audio ends [Flash8]


I have an mp3 in my library that plays when ik click a button. The button hides when the audio starts.

on (press) {
mysound = new Sound();
playbtn._visible = false;

But now I want the button to show again when the mp3 is finished. (Something with onSoundComplete?)

I’m new with Actionscripting so I’ve searched almost every website but couldn’t find the right answer. So I hope I will find it here.
