Can't get Tone.js player to work and play a single wav file

Question

无法让 Tone Player 播放任何内容，这是我的简单 VueJs 代码：

<template>
  <div>
    <h1>Simple Tone.js Demo</h1>
    <button style="background-color: cadetblue; padding: 4px 10px;" @click="play">Play</button>
  </div>
</template>

<script>
import * as Tone from "tone";

export default {
  data() {
    return {
      player: null,
    };
  },
  methods: {
    async play() {
      try {
        console.log("Tone.js context state:", Tone.context.state);
        if (Tone.context.state !== "running") {
          await Tone.start();
          console.log("audio context started");
        }
        this.player.start();
      } catch (error) {
        console.error("Error during playback:", error.message, error);
      }
    },

    async initializePlayer() {
      console.log(Tone.context.state);

      try {
        this.player = await new Tone.Player({
          url: "/sounds/rain.wav",
          loop: true,
          autostart: false,
        }).toDestination();

        this.player.loaded;
      } catch (error) {
        console.error("Error loading audio file:", error);
      }
      console.log("Audio file loaded", this.player.loaded);
    },
  },
  created() {
    this.initializePlayer();
  },
};
</script>

我正在加载的声音存在于正确的位置 sound/rain.wav 并且如果我在 chrome 中输入它的路径，浏览器能够正确打开它 http://localhost:5173/sounds/rain.wav

运行应用程序得到的输出：

了解 Tone.js 的人可以帮助我让播放器播放单个文件吗？我花了一整天的时间来解决这个问题，甚至使用了 GPT4，但我遇到了同样的问题，播放器无法播放简单的文件。

I guess the error occurred because Player has not finished downloading the audio.

The constructor does not return a promise. If you want to wait until the Player is ready, you need to pass the onload function. By wrapping it in a Promise, it can be used to wait for the Player to be ready.

this.player = await new Promise((resolve, reject) => {
    const player = new Tone.Player({
        loop: true,
        onerror: (err) => reject(err),
        onload: () => resolve(player),
        url: '/sounds/rain.wav'
    });
});

this.player.toDestination();
