Same issue in RC. It's not just MP3, it's AAC and IAM4 as well. It'll only play uncompressed PCM for some reason, but only for apps built using XCode. Even worse, anything built with XCode on previous iOS versions where it works fine will start crashing when updating to iOS 17 - so it's not a problem somehow limited to XCode 15 either. For whatever reason, apps distributed through App Store and TestFlight do not suffer from the same problem. Only direct builds to the device.

Hi, Just wanted to chime in: I'm experiencing the same problem deploying a signed IPA using XCode 15.0 Beta 4. It instantly errors out with "failed to read the bundle" (code 3000). Using XCode 14 I can deploy the same app to any iOS device without any issue. Moreover, the Apple Configurator route still indeed works as well. I hope Apple fixes this bug in XCode 15 so we may deploy directly from XCode again.
