在index. js中显示多个(音乐)文件

最近我问了一个关于保存通过multer上传的文件到mongodb的问题。我能够使其工作，但我无法在我的index. js中显示该文件。例如，我上传了一个音乐文件，当我试图在索引中显示它时。通过在路径周围包装音频标签，它显示了音频控件，但播放按钮被禁用，并且音量图标上有一个斜杠。请看我的代码

routes.js

var storage = multer.diskStorage({
destination: function (req, file, cb) {
 cb(null, './uploads/');
    },
 filename: function (req, file, cb) {
    var originalname = file.originalname;
    var extension = originalname.split(".");
    filename = Date.now() + '.' + extension[extension.length-1];
    cb(null, filename);
  }
});
router.post('/', multer({storage: storage, dest: './uploads/'}).single('uploads'), function(req,res){
  var music = new Music ({
    fieldname: req.file.fieldname,
    originalname: req.file.originalname,
    encoding: req.file.encoding,
    mimetype: req.file.mimetype,
    destination:req.file.destination,
    filename: req.file.filename,
    path: req.file.path,
    size: req.file.size
  })
  music.save(function(err){
    if (err){console.log(err)}
    else {
      res.redirect('/');
    }
  })
});

var mongoose = require('mongoose');
var musicSchema = new mongoose.Schema({
  fieldname: String,
  originalname: String,
  encoding: String,
  mimeptype: String,
  destination: String,
  filename: String,
  path: String,
  size: Number,
  created_at: Date,
  updated_at: Date
});
var Music = mongoose.model('Music', musicSchema);
module.exports = Music;

index.ejs

<form action="/" enctype="multipart/form-data" method="post">
  <input type="text" name="title">
  <input type="file" name="uploads">
  <input type="submit" value="Uploads">
</form>
<% for(var i = 0; i < musics.length; i++){ %>
  <p> <%= musics[i].originalname %> </p>
  <audio autoplay="autoplay" controls="controls">
  <audio controls="controls">
    <source src="<%= musics[i].path %>"/>
  </audio>
<%}%>

这是我的数据库中的数据
