Sound has gone on iPhone 4s
Afternoon all,
18 month old iPhone 4s, no problems whatsoever 'til this morning.
The sound is working when I turn it up high for someone ringing me.
The sound is working when I put headphones into it for music or to watch live TV or video.
The sound is NOT working when I play music or watch live TV or video when the headphones are NOT in.
Any clues greatly received.
