SimpleAudioEngine::sharedEngine()->stopAllEffects(); not working


#1

when i replace the scene ,in button click function write these lines
void GameLayer::goToMainMenu()
{

SimpleAudioEngine::sharedEngine()->stopAllEffects();
CCDirector::sharedDirector()->replaceScene(CCTransitionFadeTR::create(0.9f, MainScene::create()));

}
but both play effect from game scene and main menu scene occur together
