Hi Friend,
Try:
--Sign off/close all the apps that are running on your phone. To see all the apps, press the "Home" button twice in quick succession. Ther Home button is the square outlined button at the bottom of the phone. Scroll along, and you may be surprised to see how many apps are running.
--Press and hold an app to make it quiver. Little red circle with a minus sign should show on each running app. Turn them ALL off by pressing that little minus sign on each one. You may be surprised to see how many are running.
--Turn the phone completely off: Press and hold Sleep/Wake button for a few seconds until the red slider appears, then drag the slider. 
--Wait a few seconds and turn the phone on: Press and hold the Sleep/Wake button until the Apple logo appears. Sometimes this locks the SIM card. So have your SIM code available to unlock if necessary.
--After a couple of hours (<--This is the nail-biting part), all your sounds should (may?) magically start to return.
Hope it will be helpful
