Sound not working for iPhone 4?

I've already tried calling support and they want to charge me 19.99 for the tech support. I'm not paying for it. I don't want to make reservations for the Genius Bar either. I've already looked online and couldn't find a resolution.

The phone won't ring when getting a call, it won't ring when receiving a text, and it won't make the lock sound either. It will however let me hear calls on the phone and speakerphone, and I can also hear music through the speakerphone. The volume is on max and the vibrating is turned off. What could be the problem.

If you can't answer this question, please don't. I already know about tech support and the Genius Bar. I don't want to reset the phone either. I want to try and get some suggestions before I go through all of that and spend money. I've also tried restarting the phone multiple times.

I actually had this same problem earlier today. First, has your phone been in contact with water? If so try these steps. Take a vacuum cleaner and put the hose up to each of the speakers that are not working for like 30 seconds a piece:. Then take a q tip and take off a majority of the cotton and stick it in the headphone jack and move it around in there for a little bit. If neither of these steps work (worked for me) then take your phone, turn it off and put it in raw white rice for 24-48 hours to draw out the moisture in it.
