Since updating my iphone 4S to ios 7.1 my phone will no longer ring and apps do not have sound. I have made sure the do not disturb is not turned on and have also gone into Accessibility and made sure sound is not off there. I have done a reboot and also a reset of the settings. When I set my ring tone, the sample tone plays, however, the phone only vibrates when I get a call. The apps also do not have any sound. Everything was working fine until the update.
