When I play a m4a file on the new iOS 17 Simulator (17.0 and 17.2), the following error message appears and there is a noticeable lag on the simulator.

The error and the lag don't happen on a real device (iOS 17.2) or the 16.4 simulator. This significantly affected my development experience as when there's a sound, I can't tell whether there's a performance issue of my code or not.

Error Message: AudioQueueObject.cpp:5933 DetermineMetadataTimestamp unable to obtain valid timestamp, estimate:33506.000000

Code:

var player: AVAudioPlayer! 
let url = Bundle.main.url(forResource:"k-be", withExtension: "m4a")! 
if player != nil { player?.stop() player = nil } 
player = try AVAudioPlayer(contentsOf: url) 
guard let player = player else { return } 
player.play()

Thanks for posting, having the same issue. It's not working on my iPhone with iOS 17.3 either.

Same here, in Simulator <= 16.x it does not occur. This error also causes lag in program execution; for instance in games with multiple audio objects playing it will stall the game, rendering testing in the Simulator useless.

I am getting this error message along with "AddInstanceForFactory: No factory registered for id..." in the simulator, but no performance hit from what I can tell. However, I have encountered a slew of new performance issues on my physical device (iPhone 12, iOS 17.2.1), even before anything audio-related is initialized. I am forced to postpone audio features until this has been resolved.
