I bought a Griffin guitar cable when I picked up my iPad 3. It plugs into the headphone socket which I assume is supposed to act as an audio-in jack.
It didn't seem to work and after testing and much checking online, including the tech specs at apple.com, I was left with the impression that the iPad doesn't have a combined input & headphone output on the headphone jack (like say the 13" MBP). I took the cable back to the Apple store and the Genius guy patronised me at length and insisted that either the cable was faulty or my iPad was. I will be taking it to see them in a few days so see if there is something wrong with my iPad, but deep down, I am convinced I am right. I would appreciate someone settling this for me one way or the other. Do I need an audio interface that works via the dock or should this simple cable work with my headphone jack doubling up as a line in?
Thanks for reading.
