You open a video.
You press play.
The video runs — but there's no sound.
You check the volume. It's not muted.
You restart your PC. Still nothing.
You might think:
"Is my sound card broken? Do I need a new PC?"
Probably not.
Audio problems are one of the most common issues in Windows 11. They can happen after a Windows update, a driver conflict, a wrong setting, or just randomly.
The good news? Many audio issues can be resolved in minutes.
This guide covers 9 practical ways to fix sound problems on Windows 11 — from simple checks to driver updates.
Why Is My Audio Not Working on Windows 11?
Audio problems can happen for many reasons:
| Cause | Description |
|---|---|
| Wrong output device | Windows is sending sound to the wrong speaker or headphone |
| Muted or low volume | Sound is muted in Windows or on the device itself |
| Outdated or corrupted driver | Audio driver needs updating or reinstalling |
| Windows updates | Some updates break audio drivers |
| Disabled audio services | Windows Audio service is stopped |
| App-specific issues | One app has no sound while others work |
| Hardware problems | Loose cable, faulty speaker, or headphone jack |
| Audio enhancements | Windows audio enhancements causing conflicts |
9 Ways to Fix Audio Problems on Windows 11
Fix 1: Check the Physical Connections
Before you change any settings, check the basics:
- Is your speaker or headphone plugged in properly?
- Is the power cable connected (if using powered speakers)?
- Is the volume dial on your speaker turned up?
- Are Bluetooth headphones paired and connected?
Pro tip: Try plugging your headphones into a different device (like your phone) to verify they work.
Fix 2: Run the Audio Troubleshooter
Windows 11 has a built-in troubleshooter for audio problems.
How to run it:
- Open Settings → System → Sound
- Scroll down and click Troubleshoot common sound problems
- Follow the on-screen instructions
Alternative: Open Settings → System → Troubleshoot → Other troubleshooters → Audio → Run
What it does: This tool checks for common audio issues — like disabled services, driver problems, or wrong output devices — and attempts to fix them automatically.
Note: The exact path to the troubleshooter may vary slightly depending on your Windows 11 version and updates.
Pro tip: Run this before trying more advanced fixes.
Fix 3: Check Your Output Device
Sometimes Windows switches to the wrong output device — like sending sound to your monitor instead of your headphones.
How to check:
- Open Settings → System → Sound
- Under Output, make sure the correct device is selected
- If you see multiple options, try switching to another one
Alternative: Click the sound icon in the taskbar → click the arrow next to the volume slider → select the correct output device.
Pro tip: If the correct device isn't listed, skip to Fix 5.
Fix 4: Check Volume Levels and Mute Settings
Sometimes sound is muted — but it's not obvious.
How to check:
- Click the sound icon in the taskbar
- Make sure the master volume is not muted and is turned up
- Click the sound icon → Volume mixer (or right-click → Open Volume mixer)
- Check that your app's volume is not muted or set too low
Also check: If you're using headphones or speakers with a physical volume dial, make sure it's turned up.
Fix 5: Restart the Windows Audio Service
The Windows Audio service manages all sound on your PC. If it's stopped or stuck, sound won't work.
How to restart it:
- Press
Win + R, typeservices.msc, press Enter - Find Windows Audio
- Right-click → Restart
If the service is stopped:
- Right-click → Start
- If the service fails to start automatically, consider changing Startup type to Automatic — but only after checking that the service isn't disabled intentionally.
Pro tip: Also check Windows Audio Endpoint Builder — restart it as well.
Fix 6: Update or Reinstall Your Audio Driver
A corrupted or outdated audio driver is one of the most common causes of audio issues.
Before you start: If possible, download the latest audio driver from your PC or motherboard manufacturer's website before uninstalling the current driver.
How to update the driver:
- Open Device Manager (right-click Start → Device Manager)
- Expand Sound, video and game controllers
- Right-click your audio device → Update driver → Search automatically for drivers
If that doesn't work, reinstall the driver:
- Right-click your audio device → Uninstall device
- If Windows shows the option, check Delete the driver software for this device
- Click Uninstall
- Restart your PC
- Windows will attempt to reinstall the driver automatically
If Windows doesn't reinstall the driver: Install the driver you downloaded earlier from the manufacturer's website.
Common audio drivers/devices:
- Realtek (most common on motherboards)
- Intel (common on laptops)
- NVIDIA (HDMI audio)
- AMD (HDMI audio)
Fix 7: Disable Audio Enhancements
Windows audio enhancements can sometimes cause conflicts or poor sound quality.
How to disable them:
- Open Settings → System → Sound
- Click your output device → Properties (or Device properties)
- Under Enhancements (or Effects):
- Toggle Enhance audio to Off
- Or uncheck Enable audio enhancements
Alternative (via Control Panel):
- Open Control Panel → Sound
- Right-click your output device → Properties
- Go to the Enhancements tab
- Check Disable all enhancements
- Click Apply → OK
Fix 8: Check App-Specific Audio Settings
Sometimes one app has no sound while others work fine.
How to check:
- Click the sound icon in the taskbar → Volume mixer
- Check if the specific app is muted or set to a very low volume
- Adjust its volume
For individual apps:
- Check the app's own volume settings
- Some apps (like browsers) have their own mute buttons
- Make sure the app isn't muted in Windows Sound settings
Fix 9: Perform a System Restore (Last Resort)
If audio stopped working recently and nothing else helps, you can roll back.
How to do it:
- Press
Win + R, typerstrui.exe, press Enter - Select a restore point from before the problem started
- Follow the on-screen instructions
Note: System Restore doesn't affect your personal files — only system settings and installed programs.
