Answer 1

try it this way

final EngineOptions engineOptions = new EngineOptions(true, ScreenOrientation.LANDSCAPE_FIXED,
            new RatioResolutionPolicy(CAMERA_WIDTH, CAMERA_HEIGHT), mCamera);
    engineOptions.getAudioOptions().setNeedsSound(true);
    engineOptions.getAudioOptions().setNeedsMusic(true);
