var GameAudio = GameAudio || {
    isOpenMusic : true,

    playMusic:function(filePath, isLoop){
        if(!this.isOpenMusic) return;

    },

        jsb.AudioEngine.play2d(this.getAllPath(filePath), false, 1.0, jsb.AudioEngine.getDefaultProfile());
    },
    stopEffect:function(filePath){

    },

    stopAll:function(){
        jsb.AudioEngine.stopAll();
    },

    getAllPath:function(filePath){
        var path = "";
        if(cc.sys.os == "android"){
            path = filePath + ".ogg";
        }else{
            path = filePath + ".mp3";
        }
        return path;
    },

    getAudioEngine:function(){
        return cc.audioEngine;
    },
    
    preloadSound:function(){
        for (var i in res_sound){
            if(cc.sys.os == "android"){
                jsb.AudioEngine.preload(res_sound[i] + ".ogg", null);
            }else{
                jsb.AudioEngine.preload(res_sound[i] + ".mp3", null);
            }
        }
    }
};

PS：stopAll()在切场景更换背景音乐时使用，先停，再播。。。
