Re: The Sims 4 No Sound PC

@PelinAlp  Try uninstalling the driver you currently have through the Device Manager.  If you're online when you do this, Windows should automatically find a new driver for you.  If this doesn't help, take your computer offline first, uninstall the driver again, and install the one you downloaded from Realtek.  (Windows won't be able to find a new driver with no internet connection.)

If that doesn't help, please remove options.ini from Documents\Electronic Arts\The Sims 4.  This file holds all your in-game options, and removing it will force the game to create a new one with all default settings.  If this doesn't help, and you don't want to have to reset all your options, you can delete the new file and put the old one back.
