Why is my iPhone audio not working?

When I put my headphones in i only hear background noise and can't hear the person singing or talking. When i take the headphones out the audio doesn't work at all. I was at a waterpark yesterday and put my phone in a bag but the bag wasn't wet at all. Any answers?

This happened to me too. I didn't know what to do so I just took it to the apple store and they fixed it for me.

Umm the silent slide button on the side may be the cause… If the slider is showing orange… It is on silent. Slide it the other way to turn it off… Or it is in the sound in the settings… I had that too… Then i saw the sliding button on the side… If you don't know what i'm saying… See in google images…

  • Why does my iphone car charger make audio stop working? I have an iphone 4s and whenever I plug my car charger into it, the volume stops working entirely.

Is this normal when using a car charger?
  • Why are my iPhone videos not in sync with audio when moved on to my laptop? So when move videos i take on my iPhone 4s or iPod 4th gen to my laptop which is running Windows 7, all of the videos are not in-sync with the audio it was recorded with. They all work fine on the devices but never when I move them to my laptop. All I do is drag and drop the video files from the iPhone to my laptop. I do not use any converters.Am I doing something wrong?
  • USB/Audio Jack isn't working on my laptop? I think it's when I was carrying it the other day up to my room and my family member opened the door, it caught the side of the laptop bashing it… The USB port for my mouse doesn't work right and the audio socket only plays out of one earphone. It's not the earphones because I tried them on my iphone/ipod. So it's what happened. What can I do about this?
