Sound button not working? COCOS2D

Question

I tried this code it didn't work, I want the button to play sound when it is clicked.

-(void)starButtonsound:(id)sender
{
    [[SimpleAudioEngine sharedEngine] playEffect:@"fire_truck_1.wav"];
}

In init

starMenuItemsound = [CCMenuItemImage
                    itemWithNormalImage:@"play.png" selectedImage:@"play.png"
                    target:self selector:@selector(starButtonsound:)];
starMenuItemsound.position = ccp(525, 500);
[self addChild:starMenuItemsound z: 4];
starMenuItemsound.scale = 0.75;

Whats wrong?

Answer 1

in init

{
  // Using SpriteSheet ? Use spriteWithSpriteFrameName in place of spriteWithFile
       CCSprite *spriteNormal   = [CCSprite spriteWithFile:@"play.png"];
       CCSprite *spriteSelected   = [CCSprite spriteWithFile:@"play.png"];
       ccColor3B color = {128,128,128};
       spriteSelected.color = color;

       starMenuItemsound = [CCMenuItemImage
                        itemWithNormalSprite: spriteNormal selectedImage: spriteSelected
                        target:self selector:@selector(starButtonsound:)];
       starMenuItemsound.position = ccp(525, 500);
       starMenuItemsound.scale = 0.75;

       CCMenu *menu = [CCMenu menuWithItems: starMenuItemsound, nil];
       menu.position = ccp(0.0f,0.0f);
       [self addChild: menu z:4];
  }

Call Function:

-(void) starButtonsound:(id)sender
{
    [[SimpleAudioEngine sharedEngine] setEffectsVolume:1.0f]; //Do this in init method
    [[SimpleAudioEngine sharedEngine] playEffect:@"fire_truck_1.wav"];
}
