This should restore audio to your native Mac speakers. Try setting the sound to Internal Speakers. While you are at it, take a look at the volume bar below and make sure that your output volume is turned up and Mute is unchecked. In this tab, you should see options for choosing a sound device.
Inside the Sound settings, you will see a tab called Output. Head over to your System Preferences in the Apple Menu, and look for the Sound icon. Fortunately, this problem is easy to fix. When MacOS first boots up, it sometimes does strange things when assigning speaker outputs, which can lead to radio silence. By now, you have tried to adjust volume controls, unplugged and replugged speakers, and tried to play media on a different device, but nothing seems to work. It doesn’t matter what video or app you pull up you get nothing. In this case, you get no sound at all from the speakers that you were using before the upgrade. This is for those of you who gladly upgraded but then found that your audio had cut out completely.
