Question

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);
                }
            }

        }

    }

I think your problem is caused by “for” statements. Program will wait while for statement will end and set values after that. If you want to increase volume value parallely you should do it on ENTER_FRAME event or try Sounds fade in/out with ActionScript 3
