I have done some googling and I just can't seem to find an answer for this one... Just recently my iPhone 4's sound has stopped working. It rings, but that is all that works. It doesn't make noise when I get a text message, listen to my ipod, spotify, youtube, or netflix. When the headphones are plugged in it works fine. You'll see in the attached pictures I don't have option to turn it up. The phone isn't on mute, and when I use the volume buttons it doesn't turn it up or down. I do a hard reboot and the slider works when you open it the first time and then its done. I use Apple usb cords with apple head phones. I have an iHome that I dock it on at night for my alarm clock and I haven't docked it since I realized there was an issue, but Ill try that tonight. What I have tried: Reboot Hard Reboot Restore from Back Up Restore as New I guess if this doesn't work I will have to go to Apple, but with my current work schedule it won't be easy.
