Notifications won't make sounds on iphone?

  • Why won't my iPhone make certain sounds anymore? For some reason my iPhone is not making sounds for certain apps such as camera, or for standby mode. I checked the settings, and both "lock sounds" and "keyboard clicks" are on, yet I don't hear either of these. I know the speaker works, because it plays music and I can use speaker phone. Anyone have any clue what the problem could be? I also tried resetting the iPhone, didn't work.
