Hi! I have a music app using AVAudioEngine. Right now, I have set it up to play multi channel tracks and show "Multichannel" in the volume controls. However, I am unable to figure out how to get it to use Dolby Atmos. Is there something that needs to be enabled? Is it even possible for AVAudioEngine? I saw some apps that are able of playing with Dolby Atmos, but they do not have EQ feature, so I'm guessing that they are not using AVAudioEngine.

Hi! I'm currently developing an app that can play music stored locally. It was working fine previously, but after updating my device to iOS 17, I started getting error -54 when I try to play the file. I also noticed that when getting the list of files in MPMediaQuery.songs(), I would encounter the following errors: I suspect it might be some issue with file permissions, but I can't figure out what i am missing. I have already checked that MPMediaLibrary.authorizationStatus() is authorized. Does anyone know what the issue might be? Thank you
