Ingame sounds don't play

[Acustical]

My ingame sounds don't play, but all my settings for sound are maxed out and my volume on my laptop unmuted. The music on the radio plays, the clicking and everything plays, but sometimes the Build and Buy mode music and the burglar music doesn't play. There was a robber that completely snuck inside my house without me noticing until the alarm went off. What's wrong with my game?

Have you shut down your game and computer, then started it all back up again?

No, usually I play for a massive 8 hour session but this has been occurring most of the days I've been playing.

If you use headphones make sure the game sound is up. If you don't or its not a problem, try the computer's sound settings and make sure the sim sound isn't muted. If you haven't checked the game sound, you should do that. If all of those are fine, the best thing is to shut down the entire computer.
