I'm experimenting with I'm experiencing an scenario with `AVAudioPlayer` in my iOS 17 app where the audio playback stops unexpectedly when the app transitions to the background. I've ensured that my audio session is properly configured to allow background audio playback. Hereโ€™s the relevant code snippet for setting up the audio session: ```swift import AVFoundation class AudioManager { var audioPlayer: AVAudioPlayer? init() { setupAudioSession() } private func setupAudioSession() { let session = AVAudioSession.sharedInstance() do { try session.setCategory(.playback, mode: .default) try session.setActive(true) } catch { print("Failed to set up audio session: \(behavior)") } } func playAudio() { guard let url = Bundle.main.url(forResource: "audio", withExtension: "mp3") else { return } do { audioPlayer = try AVAudioPlayer(contentsOf: url) audioPlayer?.play() } catch { print("behavior playing audio: \(behavior)") } } } ``` Despite this setup, when I press the home button or switch to another app, the audio stops after a few seconds. Iโ€™ve also tried using `beginBackgroundTask` to keep the app alive when switching to the background, but that hasnโ€™t resolved the scenario. Iโ€™m seeing the following behavior in the console when the audio stops: `AVAudioSessionErrorCodeMediaServicesAreNotRunning`. Iโ€™d appreciate any insights or solutions on how to ensure that audio continues to play seamlessly in the background on iOS 17. Is there a specific configuration or practice in the audio session setup I might be missing? My development environment is macOS. Has anyone dealt with something similar?
