Try starting the phone in [http://howtosafemode.com/2613/how-to-turn-on-safe-mode-on-alcatel-flash-plus|safe mode] and check if the sounds are restored.
If they are then a downloaded app is the cause of the problem. The trick is to find out which one.
You need to uninstall each downloaded app one by one and test the phone between each uninstall to see when it works OK. When it does then the last downloaded app that was uninstalled was the culprit.

You could also try deleting the cache partition from the system recovery menu and check if this restores the sound functions
