How to Fix 'Could Not Start Windows Audio Service' Error

If you’re seeing the error message “Could not start the Windows Audio service on local computer,” it means your computer’s sound system isn’t functioning correctly. This issue can prevent you from hearing sounds, alerts, or music on your PC. Fixing this problem restores your audio functionality, ensuring your system’s sound features work smoothly again. Before starting, ensure you have administrator access to your computer, as some steps require elevated privileges. Also, it’s good to back up any important data just in case, though most fixes are safe. This guide provides clear, step-by-step instructions to resolve the error efficiently.

What You’ll Need

Administrator access to your Windows computer
Internet connection (optional, for updates)
Basic familiarity with Windows Services and Command Prompt (recommended)

Step-by-Step

Restart Your Computer
Begin with a simple restart. Sometimes, a quick reboot can resolve temporary glitches related to the Windows Audio service.
Check Windows Audio Service Status
Press Win + R, type services.msc, and press Enter. In the Services window, locate Windows Audio. Ensure its status is ‘Running.’ If not, right-click and select Start. If it’s already running, proceed to the next step.
Set Windows Audio Service to Automatic
In the same Services window, double-click Windows Audio. Under ‘Startup type,’ select Automatic. Click Apply and then OK. Restart your computer to see if the issue is resolved.
Restart Windows Audio Endpoint Builder Service
In the Services window, find Windows Audio Endpoint Builder. Right-click it, choose Restart. If it’s not running, right-click and select Start. Confirm both services are set to Automatic and restart your PC.
Check for Conflicting Audio Devices
Right-click the speaker icon in the taskbar and select Open Sound settings. Under ‘Output,’ ensure the correct device is selected. Disconnect any unused audio devices or Bluetooth connections that might interfere.
Update Audio Drivers
Open Device Manager by pressing Win + X and selecting Device Manager. Expand Sound, video and game controllers. Right-click your audio device and choose Update driver. Select Search automatically for updated driver software. Follow prompts and restart your computer after updates.
Run Windows Troubleshooter
Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters. Select Playing Audio and click Run the troubleshooter. Follow on-screen instructions to detect and fix issues.
Check for Windows Updates
Navigate to Settings > Update & Security > Windows Update. Click Check for updates. Install any available updates, then restart your PC.
Reset Windows Audio Service via Command Prompt
Open Command Prompt as administrator (search for ‘cmd,’ right-click, select ‘Run as administrator’). Type the following commands, pressing Enter after each:
```
net stop audiosrv
net start audiosrv
```
Then, restart your computer.
Perform System File Check (SFC)
In Command Prompt (admin), type sfc /scannow and press Enter. Wait for the scan to complete, which repairs corrupted system files that might affect services.

Common Mistakes

Forgetting to run services as an administrator, which prevents changes from applying.
Disabling the Windows Audio service instead of setting it to automatic.
Updating drivers from unreliable sources—always use official manufacturer sites or Windows Update.
Ignoring dependent services like Windows Audio Endpoint Builder, which must also be running.
Not restarting after making service or driver changes, which can leave fixes unapplied.

Tips

Always restart your PC after making changes to services or drivers to ensure they take effect.
Keep your Windows system updated to prevent compatibility issues.
Use the built-in Troubleshooter to automatically detect common audio problems.
If issues persist, consider performing a system restore to revert to a previous working state.

Troubleshooting

If the error persists after following the steps above, try these additional solutions:

Check for Hardware Issues: Test your speakers or headphones on another device to confirm they work properly.
Disable and Re-enable Audio Device: In Device Manager, right-click your audio device and select Disable device. Wait a few seconds, then right-click and select Enable device.
Perform a Clean Boot: Boot Windows with minimal startup programs to eliminate software conflicts. Instructions vary, but generally involve disabling non-Microsoft services via msconfig.
Reinstall Audio Drivers: Uninstall the current driver in Device Manager, then restart your PC. Windows will attempt to reinstall the driver automatically or download it from the manufacturer.
Reset Windows: As a last resort, consider resetting Windows or performing a clean installation if all other methods fail. Backup your data before proceeding.
