Sound Question - Fade between loops

programming flash
1

Hello,

I have a loop that plays through the first part 3/4 of the animation, at that point, I want to fade out the first loop while fading in the other.  I have managed to accomplish a fade out using.

firstSound.setVolume(95);

and decreasign the volume in a series of keyframes, however when I try to add get the other loop to start fading in before the other is done, its just doesn’t work.

In the first frame of a layer called Sound level 1 I call this.

firstSound=new Sound();
firstSound.attachSound(“0274Full”);
firstSoundVolume=100;
firstSound.setVolume(firstSoundVolume);

In the second frame of a seperate layer called background I call this…

if (playing!=true) {
_root.firstSound.start(0,999);
playing=true;
}

This works just fine, In a 3rd layer called Sound Level 2 I tried changing the attached sound like so.
.
firstSound=new Sound();
firstSound.attachSound(“0166Full”);
firstSoundVolume=0;

And then in the 1st layer bring the volume back up, that didn’t work, nor did creating a new layer and creating a new sound object call secondSound…

any advice on smoothly transitioning between loops is greatly appreciated.

My experience level is slightly above beginner.

thanks,
Clint…
