React Native Expo AV-音频未播放

Question

我正在使用expo-av库实现AudioPlayer。对于播放音频，我这样做：

import { Audio } from "expo-av";
export default function AudioPlayer() {}
AudioPlayer.playSound = async function (
source,
initialStatus = { shouldPlay: true },
onPlaybackStatusUpdate = null,
downloadFirst = true
) {
try {
// Create a complete sound object
const { sound, status } = await Audio.Sound.createAsync(
source,
initialStatus,
onPlaybackStatusUpdate,
downloadFirst
);
console.log(status);
// Play the sound
await sound.playAsync();
console.log("Sound played! Unloading from memory...");
// We are done...
// Unload the sound from memory
sound.unloadAsync();
} catch (err) {
throw err;
}
};

但是，出于某种原因，当我做时

AudioPlayer.playSound(require("../../assets/microphone-button-press.mp3"));

不播放任何声音。

我做错了什么？(在iPhone 11 pro、iOS 14上测试(

这就是我正在记录的状态对象的样子：

Object {

"durationMillis": 3120,
"hasJustBeenInterrupted": false,

"shouldPlay": true, <-----------------

在播放之前加载您的声音。

await sound.current.loadAsync(
Sounds[audioSourceWithRequire],
);
then await sound.current.playAsync();
