Fading sound doesn't work

1

Hi,

I have this problem when I try to fade in sound with the function below. It just doesn’t work and I can’t figure out where the problem is.
I would like to fade in a looping sound but nothing happens. I appreciate any hint I can get to solve this problem. Thanks in advance.

this is used to play a sound via events


dispatchEvent(new CustomEventSound(CustomEventSound.PLAY_SOUND, Main.SOUND_AMBIENT, false, true, false, 999999, 0, 0, setSoundVolume));

this is the function to play a sound. the stop-function is almost identical to this one.




public function playSound(soundName:String, isSoundTrack:Boolean = false, fadeIn:Boolean = false, fadeOut:Boolean = false,
								  loops:int = 1, offset:Number = 0, volume:Number = 1):void {
			
			if (fadeIn) {
				tempSoundTransform.volume = 0;
			} else {
				tempSoundTransform.volume = volume;
				
			}
			tempSound = sounds[soundName];
			
			if (isSoundTrack) {
				if (soundTrackChannel != null) {
					soundTrackChannel.stop();
				}
				
				soundTrackChannel = tempSound.play(offset, loops);								
				soundTrackChannel.soundTransform = tempSoundTransform;
				
				if (fadeIn) {
					for (var i:int = 0; i < fadeInInc; i++) {
						tempSoundTransform.volume += 1 / fadeInInc;
						soundTrackChannel.soundTransform = tempSoundTransform;	
						if (tempSoundTransform.volume >= 1) {
							tempSoundTransform.volume = 1;
							
						}
					}
				}
				
			} else {
				soundChannels[soundName] = tempSound.play(offset, loops);
				soundChannels[soundName].soundTransform = tempSoundTransform;
				
				if (fadeIn) {
					for (var i:int = 0; i < fadeInInc; i++) {
						
						tempSoundTransform.volume += 1/fadeInInc;
						soundChannels[soundName].soundTransform = tempSoundTransform;	
						if (tempSoundTransform.volume >= 1) {
							tempSoundTransform.volume = 1;
							
						}
						
						trace("tempSoundTransform.volume " + tempSoundTransform.volume);
					}
				}
				
			}
					
		}
