I have this too, and most recently the computer game was playing itself!! I, too, don't like loud noises. A fix to the problem is simply Run Sims4 then once it is fully booted up into the menu good to check in game volumes through the game options menu as good measure Just tap the windows home button key hard to miss its the windows logo and tab out if you are in fullscreen. At least, that's what works for me. April Here is your fix for the no sound issue in Sims4 My Dad just fixed it for me. Up test or down test freq adjustment until the sound stays on.
