No volume slider on my iPhone 4

[AnAverageGuy]

Hello everyone,

My iPhone is not letting me utilize its speakers at all, its not that there is no sound, the entire volume slider disappears if I have not selected a AirPlay device or inserted headphones. I have included some screenshots, the first is it normally, the second is from when I push the airplay button, Apple TV and Meh... are supposed to be there, but whats this "Dock Connector" thing?

It could be a wireless dock that is on your wifi network. It could also be connected to your phone via Bluetooth. In any case this kind of dock takes control of your volume and you must adjust it manually from the unit. If it is neither of these, your neighbor is probably hacking your wifi...... And I'm not sure why your headphones would be disabling your volume slider.....
