I encountered a problem when executing the following code on iOS 15. This occurs on both a simulator and a real device. In addition, this doesn't occur on iOS 14.
import AVFoundation
class MyAudio {
let audioEngine: AVAudioEngine
let audioFile: AVAudioFile
let playerNode: AVAudioPlayerNode
init() {
audioFile = try! AVAudioFile(forReading: Bundle.main.url(forResource: "sound", withExtension: "mp3")!)
audioEngine = AVAudioEngine()
playerNode = AVAudioPlayerNode()
audioEngine.attach(playerNode)
audioEngine.connect(playerNode, to: audioEngine.mainMixerNode, format: audioFile.processingFormat)
do {
try audioEngine.start()
playerNode.play()
} catch {
print(error.localizedDescription)
}
}
}
It will print these outputs.

Although these errors occur, the sounds can be played without any crashes. However, it consumes a lot of time for initializing than usual. Is there any way for resolving this problem?
