Re: Sims 4 sound repeating/lagging
@vodalapusneanu Someone else reported the same issue a couple days ago, and interestingly also only has 4 GB RAM installed. I'm not sure whether that's relevant or just a coincidence, but try playing in a clean boot:

When you reboot, don't open anything except for Origin and Sims 4.
If that alone doesn't help, try another clean boot (actually restart your computer in between), and this time, put Origin in offline mode after signing in and before opening Sims 4. Please also go through the Task Manager's background tasks list looking for any audio software; if you see a third-party app, force-close it. If this happens to bork your sound entirely, another restart will fix it, so it's not a big deal.
