I have just "upgraded" to ios7 as prompted by my deus ex machina. I use my ipad for a language course via distance education. My textbook is an iBook on the iPad with embedded audio files. Prior to the "upgrade" I could scroll backwards and forwards in an audio track. I need to be able to do this to practice words and phrases. Since the "upgrade", I have been unable to do this. I can only start and pause a track. This means that, e.g., I have to play an entire 10 minute track over and over to practice one word. My iPad is now less useful for my purposes than a 1900 wind up phonograph. Does anybody have a solution?
