innerAudioContext 安卓无法播放本音频

音频在sd卡上，同目录的图片能正常显示，文件显示存在，就是不能播放

let filePath = plus.io.convertLocalFileSystemURL(/storage/76FB-CFA0/oyuuntApp/1/1/1_1t.mp3)
let fs = plus.io.resolveLocalFileSystemURL;
fs(filePath, function(entry) {
// 如果成功获取了文件入口，那么文件存在
console.log("文件存在: " + filePath);
}, function(error) {
// 如果发生错误，通常意味着文件不存在
console.error("文件不存在或无法访问: " + filePath);
});

        this.read(filePath)
