This started when I was happily playing The Sims 3 (i have all of the expansions) and then I had something to do which made me have to minimized The Sims 3 window (i was too lazy to close the game) and when I maximized it back again, all of the sounds were gone! I thought it was just an error which could be fixed by restarting the game. But no, it didn't help. This is kind of strange though, because when I open the game, the logo, the loading screen, everything has sound EXCEPT the game. I tried to play with my other family but the same thing happen. I'm very confused. I've tried a tip from the internet to delete some caches but nothing changed. Please, can somebody help me? Playing it with no sound is just so dull.
