Audiobooks Silent After ~25 minutes In iOS 7
Hi there; I have a number of audiobooks which i brought on iTunes some years ago. I'm trying to listen to the HitchHikers Guide to the Galaxy (Douglas Adams) and Cabin Pressure (John Finnemore). Both of which after about 25 minutes of the ~3 hours of book simply become silent; everything looks like it's working the seconds keep ticking and you can go back and forth. Rewinding pre 25 minutes it plays, after 25 silence and it's in the middle of a sentence it's bizzarre. I've tried a "erase all content and settings" then restored from backup but still no joy. Is anybody else experiencing such a thing? Am happy to provide a video of what's happening if it will help to explain the issue. This problem occurred first with iOS 7 it was working just perfectly on iOS 6 (have tried the latest 7.0.3 still no better) and my old iPad is perfectly happy to play them with iOS 5.1 still.
Many thanks for help in advance.
