iPhone 4 built in speakers won't work

All media on the phone won't play sounds through the built in speakers but when I plug in the earphones I can hear it. When I connect the phone to the pc and it sync to iTunes and disconnect the sound comes back but after a while it just goes again. The Os is up to date. Could some one help me out. Thanks

iPhone 4, iOS 5.1

If you are still having the problem, take a look at the AirPlay icon to the right of where the volume slider is supposed to be. If it gives you the Play Through Dock Connector option, then you'll need to clean the dock connector. you can do this through several methods including using a business card or clean cotton swab dipped in electrical cleaner or alcohol, or pugging and unplugging the actual dock connector and juggling slightly (careful) and blowing or using canned air to try to clean out any debris.


The problem is tha that the iPhone thinks that it is still connected to the dock. A similar problem can happen witht he headphone socket.
