I tried replacing my Core Audio code for reading and decoding the music files with calls to the AV Foundation framework. I was hoping that the defunct assets.music.read-only entitlement would begin working if I used AV Foundation instead. No joy. AVAsset cannot read the file (NO == asset.readable) without the temporary path entitlement in place.
