Realtek Digital Output Has No Sound [Fixed]

Many Realtek audio device users are having problems with producing sound through the Realtek Digital Output. When it is set as the default device, the sound from the speakers connecting to their computer cannot work properly.

If you are having this issue, don’t worry. The following methods can help you bring the sound of your speakers back.

1. Set the Speakers as Default Device
2. Disable audio enhancements
3. Reinstall the Realtek audio driver
4. Update the Realtek audio driver

1. Set the Speakers as Default Device

It may not be necessary for you to use Realtek Digital Output. Digital Outputs refer to high-definition digital audio devices, which do not use regular (analog) cables to connect to computers. For example, a TV with an HDMI connection, or a high-definition audio system, like a home theater system, uses the digital output.

So if you are using regular speakers and you (or your computer) have set Realtek Digital Output as Default Device, the sound of your computer may not be able to play normally. You should set the Speakers as Default Device to get the normal sound. To do so:

on Windows 10

1. Right-click on the speaker icon on your taskbar, and then select Playback devices.
   
2. In the Sound window, select the Playback tab, right-click on Speakers, and then select Set as Default Device.
   
3. Hit OK.
   

on Windows 11

1. On your keyboard, press the Windows logo + I keys simultaneously to open Settings.
2. From the left navigation panel, select System, then click Sound from the right.
   
3. Scroll down and click More sound settings.
   
4. Under the Playback tab, right-click your speaker and select Set as Default Device.
   

Your speakers are now set as the default audio output device. If this method works for you, you will hear the sound of your computer from your speakers again.

2. Disable audio enhancements

Audio enhancement packages are aimed at enhancing your audio performance. But this feature can sometimes cause some problems. When your Realtek digital output has no sound, try disabling audio enhancements to see if it helps. Here’s how to do this:

1. On your keyboard, press the Windows logo key and R at the same time. Type in mmsys.cpl and press Enter.
   
2. Navigate to the Playback tab. Right-click your default sound device here and choose Properties. 
   
3. Navigate to the Enhancements tab, then tick the box for Disable all sound effects. Then click OK to save the change. 
   
4. For some sound cards, the options may differ. So you can try to see if there’s an Advanced tab, where you can untick the box for Enable audio enhancements.
   

Now do a test to check if disabling audio enhancements helped you solve the issues. If not, please move on.

3. Reinstall the Realtek audio driver

A wrong or incorrect Realtek audio driver could also be the culprit to the Realtek digital output not working problem. If this is your case, you can reinstall the Realtek audio driver to see if it helps. To do so:

1. On your keyboard, press the Windows key and the R key at the same time, then type devmgmt.msc and hit Enter.
   
2. Double-click to expand the Sound, video and game controllers category, then right-click your sound card and select Uninstall device.
   
3. Tick the box for Delete the driver software for this device if you’re on Windows 10, 8.1 and 7.
   
4. Tick the box for Attempt to remove the driver for this device and click Uninstall if you’re on Windows 11.
   
5. Restart your computer for the last working audio driver to be installed by Windows automatically.

If this doesn’t work for you, please move on to the next fix below.
