In this guide, we’ll delve into how to resolve Realtek audio issues in Windows 11 and pinpoint the right solution for your situation.

Several factors can lead to this issue, but it commonly arises when new devices are installed or when audio drivers are upgraded.

What Causes Realtek Audio Issues on Windows 11?

Realtek audio issues can stem from various causes on Windows 11. Below are the most prevalent reasons to help you identify the one affecting you:

The audio output is routed through the wrong channel.
Windows has outdated or corrupt drivers.
The audio output device malfunctioning.
Inaccurate audio settings.
The audio service not running or has become corrupted.

How to Fix Realtek Audio Issues in Windows 11

If you’ve recently upgraded to Windows 11, you may have noticed poorer sound quality, including issues like static, popping, or distorted noise. This is a known problem, but there are several approaches to rectify it:

Check your network connectivity
Restart the Audio service
Turn off audio enhancements
Reinstall the Audio Device
Choose another Audio format
Run the Audio Troubleshooter
Check the Audio Output
Update the Audio driver

1. Check Your Network Connectivity

Many users spend hours troubleshooting their audio systems when the issue may lie with the device or its connection. Ensure that power is reaching the output device and try reconnecting it. If your device has a mute button, confirm it’s off.

Additionally, verify that the volume is not set to the minimum on the audio output device. Try connecting the audio device to another system; if it works properly, this indicates no damage to the cables or the device.

2. Restart the Audio Service

Windows relies on three essential services for audio output; if any of them aren’t running or encounter errors, problems occur. These services include Windows Audio Endpoint Builder, Remote Procedure Call, and Windows Audio. First, check whether they are active:

Open the Start Menu, type Services, and hit Enter to launch the application.

Scroll down and double-click the Windows Audio Endpoint Builder service.

On the General tab, confirm if the service status is set to running.
If it’s not running, click the Start button.
If it is running, stop it and then restart the service.
Repeat this process for the other two services to see if it resolves your Realtek audio issues.

3. Turn Off Audio Enhancements

Audio enhancements can sometimes lead to Realtek audio problems. If you have enabled these features, it might be wise to turn them off. Here’s how:

Click Start, type Control Panel, and hit Enter.
Search for the Sound option and open it.
Navigate to the Playback tab in the new window.

Select the non-functioning speaker and click Properties at the bottom.
Go to the Enhancements tab and check the box next to Disable all enhancements.
Click OK to save the changes and then close the window to see if the audio issue is resolved.

4. Reinstall the Audio Device

If the issue continues, the audio driver may be corrupted. Reinstalling the driver can help:

Open the Run dialog by pressing Windows+R.
Look for the Realtek Audio device.
Right-click on the driver and choose Uninstall device.
Click Uninstall on the confirmation dialog.
Reboot your computer, and Windows will automatically install a new, non-corrupted driver when it restarts.

If the issue persists, proceed to the next solution.

5. Choose Another Audio Format

Audio output issues may occur if the audio format is incompatible with your hardware. To address this, try selecting a different audio format:

Search for Control Panel.
Select the Sound option.
Navigate to the Playback tab.
Select the speaker that is not functioning.
Right-click the speaker and select Properties.

In the Speakers Properties window, switch to the Advanced tab.
Under the Default Format section, choose the sample rate and bit depth from the drop-down menu.
Click the Test button and repeat until you find the format that works.
Save your changes by clicking OK.

If changing the audio format does not resolve the issue, proceed to the following fix.

6. Run the Audio Troubleshooter

The Playing Audio troubleshooter is a built-in utility in Windows 11 that can help identify and fix audio issues. Here’s how to use it:

Press Windows+I to open the Settings app.
On the System tab, scroll to the right and click the Troubleshoot option.

Next, click Other troubleshooters and locate the Playing Audio troubleshooter.
Click on the Run button next to it.
Follow the prompts to select the audio output device experiencing issues and click Next.
The troubleshooter will diagnose and attempt to fix any device or configuration problems.

During the process, follow the on-screen instructions and respond as directed.

7. Check the Audio Output

Audio problems can also occur if the incorrect output device is selected. Verify this through the Action Center:

Press Windows+A to open the Action Center.
Click the small arrow next to the volume level.
Select the appropriate playback device from the list displayed.
If this resolves the issue, set the device as the default by opening the Start menu, searching for Change system sound, and selecting the relevant result.
In the Sound window, go to the Playback tab, select your desired output device, and click Set Default.
Click OK to save your changes.

8. Update the Audio Driver

Your computer may face audio playback issues if the Realtek driver is out-of-date. To fix this, consider updating the driver manually:

Right-click the Start button and select Device Manager.
Look for the Sound, video and game controllers section and double-click it.
Right-click the Realtek(R) Audio driver and choose Update driver.
Windows will present two options: one to automatically search for the best drivers and another to manually install updates. It’s safer to choose the automatic option.
