Cocos2D对音乐/音效播放的封装已经很好了，下边是例子：

定义2个文件：

#define MUSIC_FILE        "LOLBgMusic.mp3"
#define EFFECT_FILE      "Attack.wav"

在初始化的时候预加载音乐/音效文件：

//预加载CocosDenshion::SimpleAudioEngine::sharedEngine()->preloadBackgroundMusic(MUSIC_FILE);CocosDenshion::SimpleAudioEngine::sharedEngine()->preloadEffect( EFFECT_FILE );//设置音量CocosDenshion::SimpleAudioEngine::sharedEngine()->setEffectsVolume(0.5);CocosDenshion::SimpleAudioEngine::sharedEngine()->setBackgroundMusicVolume(0.5);

播放：

       //循环播放背景音乐，CocosDenshion::SimpleAudioEngine::sharedEngine()->playBackgroundMusic(MUSIC_FILE,true);

       //播放音效CocosDenshion::SimpleAudioEngine::sharedEngine()->playEffect(EFFECT_FILE);

其他相关函数：

// stop background music
SimpleAudioEngine::sharedEngine()->stopBackgroundMusic();// pause background musicSimpleAudioEngine::sharedEngine()->pauseBackgroundMusic();
// resume background music
SimpleAudioEngine::sharedEngine()->resumeBackgroundMusic();
// rewind background music
SimpleAudioEngine::sharedEngine()->rewindBackgroundMusic();
// is background music playing
SimpleAudioEngine::sharedEngine()->isBackgroundMusicPlaying()
// add bakcground music volume
SimpleAudioEngine::sharedEngine()->setBackgroundMusicVolume(SimpleAudioEngine::sharedEngine()->getBackgroundMusicVolume() + 0.1f);SimpleAudioEngine::sharedEngine()->pauseEffect(m_nSoundId);
SimpleAudioEngine::sharedEngine()->resumeEffect(m_nSoundId);
SimpleAudioEngine::sharedEngine()->pauseAllEffects();
SimpleAudioEngine::sharedEngine()->resumeAllEffects();
SimpleAudioEngine::sharedEngine()->stopAllEffects();
