Sound issue after downloading openfl 4.9.1 and lime 4.0.2

it’s worst than i thought.
I have to play a fake sound and to stop it before it ends although it doesn’t work

`

aideSound = Assets.getSound (“audio/aide.mp3”);
fakeSound = Assets.getSound (“audio/fake.mp3”);
channel = new SoundChannel();
tranformSound = new SoundTransform();
Actuate.timer(.5).onComplete(init);
jouer(fakeSound);
}

private function init() {
channel.stop();
jouer(aideSound);

`
