How to fix error no-sound-on-windows-pc in Windows 11

Solution Steps

1. 1 First, check the basics: Ensure your speakers or headphones are properly connected and powered on. Check the volume icon in the system tray (bottom-right corner) and make sure it's not muted. Click the speaker icon and drag the volume slider up.
2. 2 Press Windows key + I to open Settings. Go to System → Sound. Under Output, look at the 'Choose where to play sound' dropdown. Make sure the correct device is selected (e.g., 'Speakers' or 'Headphones'). If you see multiple devices, try switching to each one to see if sound comes out.
3. 3 If the correct device is selected but there's still no sound, run the built-in audio troubleshooter: In Settings → System → Sound, scroll down and click 'Troubleshoot' under 'Advanced'. Windows will automatically detect and fix common audio problems.
4. 4 Check if the Windows Audio service is running: Press Windows key + R, type 'services.msc', and press Enter. Scroll down to 'Windows Audio'. Double-click it, ensure the Startup type is 'Automatic' and the service status is 'Running'. If not, click Start. Also check 'Windows Audio Endpoint Builder' and set it to Automatic and Running.
5. 5 Update your audio driver: Press Windows key + X and select 'Device Manager'. Expand 'Sound, video and game controllers'. Right-click your audio device (e.g., 'Realtek High Definition Audio') and select 'Update driver'. Choose 'Search automatically for drivers'. If Windows doesn't find a new one, visit your PC manufacturer's website to download the latest audio driver.
6. 6 If updating doesn't work, uninstall the audio driver: In Device Manager, right-click the audio device and select 'Uninstall device'. Check 'Delete the driver software for this device' if available, then restart your PC. Windows will reinstall the driver automatically.
7. 7 Check if the audio device is disabled: In Device Manager, if you see a down arrow on the audio device, right-click it and select 'Enable device'.
8. 8 If you're using HDMI or DisplayPort for audio, ensure the monitor's speakers are selected as the output device and that the monitor's volume is not muted.
9. 9 If all else fails, try a system restore: Press Windows key + R, type 'rstrui', and press Enter. Choose a restore point from before the audio issue started and follow the prompts.
