The volume bar has disappeared. There's no sound in apps.
When I press the + and - buttons, the volume icon appears, but the slider is empty. When I receive a call, I hear it ring, and I can hear the ringtones in the sound menu. However, the message/mail notifications don't make any noise, and I can't hear the sound menu.
I changed my LCD screen and upgraded my iPhone 4 to iOS 5 the same day. Now, I have a strange problem, and I don't know if the cause is an iOS 5 bug or a physical problem.
I restored the device many times on iOS 5, but it doesn't fix the problem. Here are some other symptoms:
- During a phone call, if I put the conversation on speakers, it works and the volume bar reappears. I can control the volume with the + and - buttons. But when the conversation is over, the bar disappears again.
- With the headphones, everything is ok!
- I also noticed (only a few times) that when I do a repring (with changing the language of the phone), the volume slider reappears and works correctly for 2 or 3 seconds, before disappearing again.
My guess is that this is an iOS 5 problem, since the speakers work.
Can you please help me?
Thanks from Paris.
