This is weird, when I record a video clip with my iphone 5, and then play it back, all I get is static! Sound does work with the speakers when I am playing a game or using the speakerphone. When I tried to play an mp3, via double clicking on the home, then swiping to the ipod controls, it had the same result. When I went to the music app it worked, then the ipod controls worked fine.
Incidently I believe this is the first time I tried testing this after I replaced my iphone 5 because of cosmetic blemishes. The original worked with the audio no problem. Any ideas?
OK here is an update, the problem was the back "screen" protector I put on the iphone 5. It covered the hole between the camera and the flash. Once I removed the protector the audio recording worked fine again.
