Hi, I've been trying to play an audio asset (.m4a) using an AVAudioPlayer, but results in what I believe is an internal error. I've been using the following code to load and play the asset. Please note that the code was run using an iPad Pro 11-inch simulator with iPadOS 14 in Xcode 12 beta. guard let audioData = NSDataAsset(name: "Example")?.data else {     fatalError("Asset not found") } do {     let audioPlayer = try AVAudioPlayer(data: audioData, fileTypeHint: "m4a")     audioPlayer.play() } catch {     fatalError(error.localizedDescription) } The catch block is not reached, but the audio does not play and the console logs the following: 2020-06-26 14:48:25.784066-0500 Name[45441:2235216]  HALB_IOBufferManager_Client::GetIOBuffer: the stream index is out of range 2020-06-26 14:48:25.784551-0500 Name[45441:2235216]  HALB_IOBufferManager_Client::GetIOBuffer: the stream index is out of range 2020-06-26 14:48:25.796707-0500 Name[45441:2235216] [aqme] 255: AQDefaultDevice (1): output stream 0: null buffer 2020-06-26 14:48:25.797137-0500 Name[45441:2235216] [aqme] 1778: EXCEPTION thrown (-50): error != 0 Can you please let me know if there's something wrong with the way I'm loading/playing the asset or if this looks like an internal bug in the betas?
