How to Fix Audio Inputs and Outputs Missing from Device Manager

The Audio inputs and outputs section in Device Manager is essential for managing microphones, speakers, headsets, and other sound devices in Windows 11. If this category is missing entirely, audio devices may not work, sound settings may appear empty, or Windows may fail to detect microphones and speakers.

This issue usually occurs due to corrupted or missing audio drivers, disabled Windows audio services, incorrect BIOS settings, or system file corruption after Windows updates. In some cases, the devices still exist, but Windows is unable to enumerate them correctly.

Fixing missing audio inputs and outputs in Device Manager requires restoring audio services, reinstalling drivers, and ensuring Windows is correctly detecting audio hardware. The steps below explain how to resolve the issue safely and effectively.

How to Fix Audio Inputs and Outputs Missing from Device Manager

The methods in this section focus on restoring audio device detection and repairing Windows audio components. Follow the steps in order and check Device Manager after each method.

1. Restart Windows Audio Services

Audio services must be running for devices to appear.

1. Press Windows + R, type services.msc, and press Enter.
2. Locate Windows Audio.
3. Right-click it and select Restart.
4. Locate Windows Audio Endpoint Builder.
5. Restart it as well.
6. Ensure both services are set to Automatic.

If these services are stopped, audio devices will not be listed.

2. Show Hidden Devices in Device Manager

Audio devices may be hidden.

1. Press Windows + X and open Device Manager.
2. Click View in the top menu.
3. Select Show hidden devices.
4. Check if Audio inputs and outputs appears.

Hidden or disconnected devices may become visible.

3. Scan for Hardware Changes

Windows may need to re-detect audio hardware.

1. Open Device Manager.
2. Click Action.
3. Select Scan for hardware changes.
4. Wait for Windows to refresh the device list.

This forces Windows to re-enumerate hardware.

4. Reinstall Audio Drivers

Corrupted drivers commonly cause this issue.

1. Open Device Manager.
2. Expand Sound, video and game controllers.
3. Right-click your audio device (Realtek, Intel, or similar).
4. Select Uninstall device.
5. Check Delete the driver software for this device if available.
6. Restart the computer.

Windows will reinstall default audio drivers automatically.

5. Install Audio Drivers from Manufacturer

Generic drivers may not restore all components.

1. Identify your PC or motherboard model.
2. Visit the manufacturer’s official website.
3. Download the latest Windows 11 audio drivers.
4. Install the drivers.
5. Restart the computer.

Manufacturer drivers ensure full device support.

6. Enable Audio Devices in BIOS or UEFI

Audio hardware may be disabled at firmware level.

1. Restart the computer.
2. Enter BIOS or UEFI settings.
3. Locate Onboard Audio, HD Audio, or Azalia Audio.
4. Ensure it is Enabled.
5. Save changes and exit.

Disabled onboard audio will not appear in Windows.

7. Run Windows Audio Troubleshooter

Built-in troubleshooting can fix configuration issues.

1. Open Settings.
2. Go to System.
3. Select Sound.
4. Scroll down and click Troubleshoot.
5. Follow the on-screen instructions.

The troubleshooter resets audio components automatically.

8. Repair Corrupted System Files

System file corruption can hide device categories.

1. Open Terminal (Admin).
2. Run the following command: sfc /scannow
3. After it completes, run: DISM /Online /Cleanup-Image /RestoreHealth
4. Restart the computer.

These tools repair core Windows components.

9. Check Windows Update and Optional Driver Updates

Audio drivers may be available through Windows Update.

1. Open Settings.
2. Go to Windows Update.
3. Click Advanced options.
4. Select Optional updates.
5. Install any available audio or driver updates.
6. Restart the system.

Optional updates often include missing drivers.

10. Reset Windows Audio Configuration (Last Resort)

Persistent issues may require deeper reset.

1. Uninstall all audio-related drivers.
2. Restart Windows.
3. Reinstall official audio drivers.
4. Reboot and recheck Device Manager.

This rebuilds the entire audio stack.

Final Thoughts

Audio inputs and outputs missing from Device Manager in Windows 11 is usually caused by disabled audio services, missing drivers, or system corruption rather than faulty hardware. In most cases, restarting audio services or reinstalling the correct audio driver restores the missing category immediately.
