It’s exasperating when you’re trying to play music or games and your Realtek Digital Output device has no sound coming out. To help you resolve this issue, we’ll introduce three ways for you in this guide.

  1. Reinstall your audio driver
  2. Enable Realtek Audio Manager at Startup

Before we start troubleshooting, please check that your Realtek Digital Output devices (such as TV or Home Theatre system) are connected properly, as the only way to resolve the loose connection issue is to give it a little bit more push. Also, please note that regular speakers or headphones must use analog wires rather than digital cables to get connected, as they are NOT Realtek Digital Output devices. Then, proceed with the steps below.

1. Reinstall your audio driver

When you hear no sound from your Realtek Digital Output devices, one of the first things you should do is to reinstall your Realtek audio driver, since an up-to-date audio driver always ensures the best audio performance and fewer bugs.

To update your audio card driver, here’s what you can do (please note that the following screenshots are taken on Windows 11, but the instructions work on Windows 10 as well):

  1. On your keyboard, press the Windows key and X at the same time, select Device Manager.
  2. Double-click to expand the category Sound, video and game controllers. Then right-click your Realtek HD audio driver and click Uninstall Device.
  3. If you’re prompted to confirm the uninstallation, click OK.

Once done, you can restart your computer and Windows will automatically reinstall the driver for you. Either way, you can consider reinstalling your Realtek HD Audio Driver in a different way with the help of Driver Techie.

2. Enable Realtek HD Audio Manager at Startup

If Realtek HD Audio Manager is mistakenly disabled, your Realtek digital output device will probably have no sound. Go through the steps below to check if your Realtek HD Audio Manager is enabled.

  1. On your keyboard, press the Windows logo key and X together and select Task Manager.
  2. Click the Startup tab from the top menu, and then look for Realtek HD Audio Manager from the list.
  3. If you see Realtek HD Audio Manager is disabled, right-click it and select Enable. (If you don’t see it, then you’re not using it, or it’s missing. Kindly refer to this post to see how to install it.)
  4. Restart your computer.

Hopefully, your Realtek digital output will soon come back to work. If you have any other questions, please feel free to leave a comment below.
