If you are experiencing sound problems with your phone such as you are missing a volume bar when you are watching a video or listening to music then your phone thinks it is DOCKED! You could have dropped your phone, got it wet, or there is lint and dust in your dock port. Try this steps first as it does not require any jail break or taking the phone apart. Please note I am not responsible if you damage your phone. If you guys need help let me know. If this does not work then you may want to look into buying a dock connector kit. Its less then $10 and easy to install. Id advise getting the tools with it too. You can see what it looks like from the links below. Thanks for watching.
