volume buttons do not work on iphone 4s
Hi I have an iphone 4s and the volume buttons do not work on the side for any kind of media playback. I can get sound for texts, calls etc but when I try to play video, music they just do not appear. This was an intermittent problem where I could reset the phone and they would come back or if I docked the phone I could get it to playback but now nothing happens at all.
iPhone 4S, iOS 7.0.4
