Question

How to check reliably if a SoundChannel is still playing a sound?

For example,

[Embed(source='song.mp3')] var Song: Class;  var s: Song = new Song(); var ch: SoundChannel = s.play();  // how to check if ch is playing? 

Answer 1

I’ve done a little research and I can’t find a way to query any object to determine if a sound is playing. You’ll have to write a wrapper class and manage it yourself it seems.

 package {     import flash.events.Event;     import flash.media.Sound;     import flash.media.SoundChannel;      public class SoundPlayer     {         [Embed(source='song.mp3')]         private var Song:Class;          private var s:Song;         private var ch:SoundChannel;         private var isSoundPlaying:Boolean;          public function SoundPlayer()         {             s = new Song();             play();         }          public function play():void         {             if(!isPlaying)             {                 ch = s.play();                 ch.addEventListener(                     Event.SOUND_COMPLETE,                     handleSoundComplete);                 isSoundPlaying = true;             }         }          public function stop():void         {             if(isPlaying)             {                 ch.stop();                 isSoundPlaying = false;             }         }          private function handleSoundComplete(ev:Event):void         {             isSoundPlaying = false;         }     } }
