RT.播放音效看到onError回调输出：res= Object { errCode: 10001, errMsg: "errCode:602, err:error, not found param" }；

10001显示是系统错误码。那我该怎么解决呢？mp3文件是通过格式工厂转码成44100Hz，96kbps的了？

let audio = wx.createInnerAudioContext();
audio.src = "https://cdnhotpot.fengmigame.com/tencent_wx/debug/v2/res/sound/mp3/clear.mp3";
audio.play();
audio.onError((res)=>{
                console.log("音效播放错误 playSound onError res=",res);
            });
