暂停反应本机博览会音频？

我运行音频没有问题，但暂停它时遇到问题。如果有人可以提供帮助那就太好了。

async function playMusic() {
  const soundObject = new Audio.Sound();
  console.log("Being hit")

  try {
    await soundObject.loadAsync({uri:'https://firebasestorage.googleapis.com/v0/b/o/myFolder%2FMello%20C%20-%20Easy.mp3?c4e-4bf8-b8ea-dcc201efff44'});
    await soundObject.playAsync();
  } catch (error) {
    alert("Error" + error.message)
  }
}

async function stopMusic() {
  console.log("Not Being hit")
 const soundObject = new Audio.Sound();

 try {
   await soundObject.loadAsync({uri:'https://firebasestorage.googleapis.com/v03?alt=media&token=e44f7b2f-8c4e-4bf8-b8ea-dcc201efff44'});
   await soundObject.stopAsync();
 } catch (error) {
   alert("Error" + error.message)
 }
}

请注意，我们永远不应该创建 Sound 实例作为状态变量。因为每当重新渲染时，它都会重新初始化声音实例。

你应该创建一个ref变量并使用它，

const sound = React.useRef(new Audio.Sound());
