如何避免AVPlayer上设备静音控制的影响

import AVFoundation

let audioSession = AVAudioSession.sharedInstance()
do {
    try audioSession.setCategory(.playback)
    try audioSession.setActive(true)
} catch {
    print("Failed to set audio session category and active: \(error)")
}

import MediaPlayer

let volumeView = MPVolumeView(frame: CGRect(x: 0, y: 0, width: 100, height: 100))
view.addSubview(volumeView)

import AVFoundation

let player = AVPlayer(url: URL(string: "https://example.com/video.mp4")!)
let playerLayer = AVPlayerLayer(player: player)
playerLayer.frame = view.bounds
view.layer.addSublayer(playerLayer)

player.play()

playerLayer.volume = 1.0 // 设置音量
