Hello @Roman_Pacheco1,
Sorry about the slight delay in getting back to you. Can you please try to uninstall your Realtek driver through Device Manager and see if that solves the issue? We have had reports from users saying that after uninstalling the drivers, sound works again link #1, link #2. After you have uninstalled the driver please check again if sound is working. If it is now working you can then try updating to the newest ones from the Realtek site and see if it still works (Manufacturer sites don’t always have the newest drivers). A guide to uninstalling drivers can be found here link (though in your case it wouldn’t be the drivers for a mouse but for the Realtek audio device). Can you let me know if that solves the issue?
Thanks,
Noris
