Why Audio Stops Working in Windows 11
Audio issues in Windows 11 PC can occur due to various causes, including driver problems, system updates, incorrect settings, or hardware faults.
- Outdated, missing, or corrupted audio drivers
- Muted volume or incorrect output device selection
- Disabled Windows audio services
- Audio enhancements are interfering with playback
- Hardware connection issues (e.g., loose cables or faulty ports)
- Bugs introduced by Windows updates
Check Volume and Audio Output Device
This may sound simple, but in many cases, the issue is nothing more than muted audio or the wrong playback device being selected. If your Laptop’s sound is not working, it may be because Windows is sending audio to a disconnected device like an HDMI monitor. Selecting the correct output usually resolves this instantly.
- Click the Volume icon in the taskbar.
- Adjust the slider to make sure the sound is not muted or set too low.
- Click the small arrow next to the slider and select the correct output device (e.g., “Speakers (Realtek)” or “Headphones”).
If you are using an external audio device (headphones or speakers), ensure it is powered on and properly connected.
Restart Your Computer
A restart refreshes Windows services and clears temporary glitches that may cause Windows audio not working. For example, if a background process conflicts with your sound driver or if an update didn’t apply correctly, rebooting helps restore normal operation.
- Save your work and restart your PC.
- After reboot, test audio playback with a video, music file, or system sound.
This basic step may seem too simple, but surprisingly, it resolves a number of sound-related issues.
Run the Windows Audio Troubleshooter
Windows 11 includes built-in troubleshooters designed to automatically detect and fix common issues. Running the Audio troubleshooter checks your sound device, identifies misconfigurations, and applies recommended fixes.
- Open Settings using Windows key + I.
- Go to System > Troubleshoot > Other troubleshooters.
- Find Playing Audio and click Run.
If the troubleshooter detects problems (like incorrect audio device selection, driver issues, or disabled services), it will attempt to fix them automatically.
Restart Windows Audio Services
Windows uses background services to handle sound playback. If these services stop running due to a glitch, you’ll face computer sound not working issues. Well, starting or restarting audio services restores sound functionality.
- Press Win + R, type services.msc, and press Enter.
- In the Services window, find Windows Audio.
- Right-click and choose Restart.
- Do the same for Windows Audio Endpoint Builder.
If the service is not started, Right-click each, select Properties, and set Startup type to Automatic and click Start next to service status.
This ensures that Windows has restarted its audio engine and re-established the connection with your sound device.
Update or Reinstall Audio Drivers

Update Drivers:

- Expand Sound, video and game controllers.
- Right-click your audio device (e.g., Realtek, Intel, or NVIDIA HD Audio).
- Select Update driver > Search automatically for drivers.
Reinstall Drivers:
If updating doesn’t work, uninstalling and reinstalling ensures a clean setup.
- In Device Manager, right-click your audio device.
- Choose Uninstall device.

Alternatively, visit your PC manufacturer’s website (e.g., Dell, HP, Lenovo) or audio chipset provider (Realtek, Intel) to download and install the latest driver manually.
If your computer’s sound is not working after a Windows update, reinstalling drivers is the most effective fix.
Disable Audio Enhancements
Audio enhancements can sometimes cause playback issues.
- Right-click the speaker icon and select Sounds settings
- Scroll down and under the Advanced section, click on More sound settings.
- Under the Playback tab, double-click your default device.
- Navigate to the Enhancements tab.

Check Hardware Connections

- Ensure external speakers or headphones are connected properly.
- Try a different audio jack or USB port.
- Test with another pair of headphones or speakers to confirm if it’s a hardware issue.
- If using HDMI or DisplayPort audio, verify the cable and display settings.
- For Bluetooth devices, make sure they are paired and connected in Windows settings.
Use System Restore
If you notice the problem started after a recent system change or update, restoring your system to an earlier state can help. This feature rolls back Windows settings, drivers, and system files to a previous configuration when your audio was working fine.
- Open Control Panel > Recovery.
- Select Open System Restore.
- Choose a restore point from before the sound stopped working.
Note: System restore won’t delete personal files, it may remove apps or drivers installed after that restore point, so use it as a last resort.
