Hi, I have googled this a little, but sadly nothing seems to have helped. This morning, my phone was working fine, and halfway through the day I noticed the sound wasn't working. It is not in silent mode, and nothing has happened to it. It was working in my pocket, it suddenly was no longer. Ringer sound, app sound, music sound, all not working. The phone function is normal. I've tried all the trouble shoots I can find, like plugging earphones in and the charger, but that didn't help. I have also done a full reset and restore and it's still without sound. It's an iPhone 5 which I've had since November. Never had any problems until today. I really appreciate any advice anyone has.
