Expo: expo-av is deprecated and unmaintained (removed from Expo Go in SDK 55) — use expo-audio and expo-video

npx expo install expo-audio expo-video
npm rm expo-av

Audio:

// before
const { sound } = await Audio.Sound.createAsync(require('./assets/hello.mp3'))
await sound.playAsync()

// after
import { useAudioPlayer } from 'expo-audio'
const player = useAudioPlayer(require('./assets/hello.mp3'))
// <Button title="Play" onPress={() => player.play()} />
// replay: player.seekTo(0); player.play()

Video:

import { useVideoPlayer, VideoView } from 'expo-video'

const player = useVideoPlayer(videoSource, (p) => { p.loop = true; p.play() })
return <VideoView player={player} style={{ width: 350, height: 275 }} fullscreenOptions={{ enable: true }} allowsPictureInPicture />

In SDK 55 the allowsFullscreen prop of VideoView was removed; use fullscreenOptions={{ enable: true }}.
