How to Fix “No Audio Output Device Installed” Error on Windows 11: Step-by-Step Solutions

Experiencing the “No Audio Output Device Installed” error on Windows 11 can be frustrating, especially when you want to listen to music or attend a meeting. This issue typically means your computer is not detecting your sound hardware correctly. Fortunately, there are several simple steps you can take to fix the problem.

In this guide, we will walk you through straightforward solutions to get your audio working again. Each step is explained clearly, so even if you’re not very tech-savvy, you can follow along with ease.

By the end, you should be able to restore sound on your computer without needing professional help. Let’s start with some quick checks before diving into the fixes.

Keep in mind, sometimes the problem may be hardware related, but most often, it’s something you can solve on your own.

Quick Note: What to Check Before Starting

Ensure your speakers or headphones are properly connected. Loose cables or faulty connections can cause no audio output.
Check if the sound is muted or volume is very low. Look at the speaker icon on the taskbar and adjust volume settings.
Restart your computer. A simple reboot can fix temporary glitches.
Confirm Windows 11 is up to date. Updates often include fixes for hardware problems.

Step 1: Run the Windows Audio Troubleshooter

Windows 11 includes a built-in troubleshooter to detect and fix common sound issues automatically. This is often the quickest way to resolve audio problems.

Click on the Start button and select Settings.
Navigate to System > Sound.
Scroll down and click on Troubleshoot under the “Advanced” section.
Follow the on-screen instructions. Windows will scan for issues and try to fix them.

This step is important because it can automatically detect if a service is disabled or if there are driver problems.

Step 2: Check and Restart Windows Audio Services

Windows relies on specific services to manage audio hardware. If these services stop or malfunction, your audio device may not be recognized.

Press Win + R on your keyboard to open the Run dialog.
Type services.msc and press Enter to open the Services window.
Scroll down and find Windows Audio.
Right-click on it and select Restart. If it’s not running, choose Start.
Also, find Windows Audio Endpoint Builder and restart it in the same way.

Restarting these services can re-establish communication between Windows and your audio hardware.

Step 3: Update or Reinstall Audio Drivers

Audio drivers are software that allow Windows to work with your sound hardware. Outdated or corrupted drivers often cause the “No Audio Output Device Installed” error.

Right-click on the Start button and select Device Manager.
Expand the section labeled Sound, video and game controllers.
If you see a yellow exclamation mark next to your audio device, that indicates a problem.
Right-click on your audio device and select Update driver.
Choose Search automatically for drivers to let Windows find the latest version.
If updating doesn’t work, right-click again and select Uninstall device. Then restart your PC. Windows will try to reinstall the driver automatically.

Updating or reinstalling drivers ensures your system has the correct software to communicate with your audio hardware.

Step 4: Show Disabled and Hidden Devices in Sound Settings

Sometimes, Windows may disable audio devices or hide them from the list, causing the system to think no device is installed.

Right-click the speaker icon in the system tray and choose Sound settings.
Scroll down and click More sound settings.
In the Playback tab, right-click anywhere in the empty space and ensure both Show Disabled Devices and Show Disconnected Devices are checked.
If your audio device appears in the list but is greyed out, right-click it and select Enable.
Set it as the default device by right-clicking and choosing Set as Default Device.

Enabling hidden devices can bring back audio hardware that Windows has mistakenly disabled.

Step 5: Check BIOS Settings (Advanced)

In rare cases, your audio device might be disabled at the motherboard or BIOS level. This is more advanced but worth checking if previous steps fail.

Restart your computer and enter the BIOS/UEFI setup by pressing the appropriate key (usually F2, Delete, or Esc during startup).
Look for settings related to onboard audio or integrated peripherals.
Make sure the audio device is enabled.
Save and exit the BIOS.

Disabling onboard audio in BIOS prevents Windows from detecting sound hardware, so this step ensures it is active.

Alternative Methods and Advanced Options

If the above steps don’t work, try the following:

System Restore: Use Windows’ System Restore feature to revert your system to a point when audio was working.
Update Windows: Go to Settings > Windows Update and check for the latest updates.
Use Third-Party Driver Tools: Some tools can scan and fix driver issues automatically (use trusted software only).
Reset Windows: As a last resort, resetting Windows can fix deep system issues but will require backing up your data.
