How to Fix Audio Output Not Working in Windows 11: Step-by-Step Troubleshooting Guide

Audio output problems in Windows 11 can be frustrating, especially when you need sound for work or entertainment. Fortunately, most issues can be fixed with a few simple steps. This guide will walk you through easy ways to troubleshoot and restore your sound.

Whether your speakers or headphones are not producing sound, or your system shows no audio device, there is a solution. We will start from the most basic checks and move towards advanced fixes.

By following these instructions carefully, you can identify the root cause and get your audio working again quickly. No technical background is needed—just a little patience and step-by-step guidance.

Let’s begin with some quick notes to ensure you have everything ready before troubleshooting.

Quick Note: Before You Start Troubleshooting

  • Check your physical connections: Make sure your speakers or headphones are properly plugged in. Loose cables are a common cause of no sound.
  • Volume settings: Confirm that your volume is not muted or set too low on both your device and Windows.
  • Audio device selection: If you have multiple audio devices, ensure the correct one is set as default.
  • Windows updates: Having the latest updates can fix bugs that cause audio problems.

Step 1: Restart Your Computer

Sometimes the simplest solution works best. Restarting your computer refreshes system processes and can resolve temporary glitches affecting audio.

How to restart:

  1. Click the Start button.
  2. Select Power.
  3. Click Restart.

After your PC restarts, check if the audio is working.

Step 2: Check Volume and Mute Settings

Windows and your external devices have volume controls that can mute sound. Here’s how to verify:

  • Look at the speaker icon in the taskbar. Click it and make sure the volume slider is up and not muted.
  • If you use external speakers or headphones, check their volume buttons or switches.
  • Try increasing the volume and test the sound again.

Step 3: Set the Correct Audio Output Device

Windows may be sending sound to the wrong device, especially if you use multiple audio devices.

Follow these steps:

  1. Click the speaker icon in the taskbar.
  2. Click the arrow or device name above the volume slider to see available audio devices.
  3. Select the device you want to use (e.g., speakers or headphones).

Testing after this can confirm if the correct device is selected.

Step 4: Run the Windows Audio Troubleshooter

Windows has a built-in troubleshooter that automatically detects and fixes common audio issues.

To run it:

  1. Open Settings by pressing Windows + I.
  2. Go to System > Sound.
  3. Scroll down and click Troubleshoot common sound problems.
  4. The troubleshooter will scan and suggest fixes. Follow the on-screen prompts.

This tool is helpful because it checks multiple settings and services quickly.

Step 5: Update or Reinstall Audio Drivers

Audio drivers are the software that connects Windows to your sound hardware. Outdated or corrupted drivers can cause no audio.

To update or reinstall drivers:

  1. Press Windows + X and select Device Manager.
  2. Expand the Sound, video and game controllers section.
  3. Right-click your audio device (for example, “Realtek High Definition Audio”) and choose Update driver.
  4. Select Search automatically for updated driver software.
  5. If no update is found, or updating doesn’t help, right-click again and choose Uninstall device. Restart your computer to let Windows reinstall the driver automatically.

Keeping drivers current ensures compatibility and better performance.

Step 6: Check Windows Audio Services

Windows uses services to manage audio. If these services are stopped, sound won’t work.

Here is how to check:

  1. Press Windows + R to open the Run dialog.
  2. Type services.msc and press Enter.
  3. In the Services window, find Windows Audio.
  4. Right-click it and select Properties.
  5. Make sure the Startup type is set to Automatic.
  6. If the service is not running, click Start.
  7. Also check Windows Audio Endpoint Builder and repeat the above steps.
  8. Click OK and close the window.

This ensures audio services are active and ready to manage sound.

Step 7: Disable Audio Enhancements

Sometimes audio enhancements can cause problems by interfering with the normal sound output.

To disable enhancements:

  1. Right-click the speaker icon in the taskbar and select Sound settings.
  2. Under Output, click your audio device.
  3. Scroll down and click Advanced or Device properties.
  4. Find the Enhancements tab or section.
  5. Check the box that says Disable all enhancements or uncheck all enhancement options.
  6. Click Apply and then OK.

Try playing audio again to see if this resolves the issue.

Step 8: Check for Windows Updates

Microsoft regularly releases updates that fix bugs and improve system stability, including audio components.

To check for updates:

  1. Open Settings (Windows + I).
  2. Go to Windows Update.
  3. Click Check for updates.
  4. Download and install any available updates.
  5. Restart your PC if prompted.

Installing updates ensures your system is running the latest fixes.

Step 9: Advanced Option – Use System Restore

If the audio stopped working recently after changes or updates, you can restore your system to an earlier point when sound was working.

To use System Restore:

  1. Search for Create a restore point in the Start menu and open it.
  2. Click System Restore.
  3. Follow the wizard to select a restore point dated before the audio issue began.
  4. Confirm and wait for the system to restore.

This will undo recent changes that might have caused the problem.
