Hey Forum, So I've been dealing with this issue for a long time now waiting and waiting until I can make it to an Apple Store to get my iPhone replaced. However, I figured maybe there is someone out there with a similar problem and I could get this fixed sooner. My issue is that my iPhone 4 won't make any sound at all, minus alarms. I attached three screenshots of what my screen shows in Settings >> Sounds. I don't have a picture of my ring/vibrate switch but honestly it doesn't even matter. When I flip the switch, my iPhone doesn't do anything at all: no vibration going into silent, no icon, no nothing. It does still vibrate thankfully, so I can feel calls, texts, emails, etc. Weird thing, I can still hear my alarms. Every morning it will wake me up but never sound when I want something else. I also can not hear YouTube videos or my iPod or recorded videos without headphones or an external device. Another symptom is the disappearance of my volume bar altogether, as shown in the final screen shot. My theory is that the iPhone thinks it is plugged into an external device of some sort.. Like a car stereo or sound peripheral in general. Also, to qualm any ideas of damage or anything, the iPhone is in an Otter Box Defender and has been ever since its purchase in July 2011. Restores don't work either. Anyone have any thoughts/suggestions/questions?
