Computer has no sound? Learn 7 ways to fix audio problems on Windows 10/11. Complete step-by-step guide + automatic AI fix.

Why Does My PC Have No Sound?

Audio problems on Windows are extremely common and can have various causes: outdated drivers, stopped audio service, wrong output device selected, or misconfigured settings.

The good news is that most of these problems have simple solutions. Here are the 7 most effective fixes:

1. Check Volume and Output Device

It seems obvious, but often the problem is simply the volume being muted or the wrong output device selected.

Click the sound icon in the system tray (bottom right corner)

Check if the volume isn't at 0 or muted

Click the arrow next to the volume control to choose the correct output device

2. Restart Windows Audio Service

The Windows Audio service can crash or stop. Restarting it fixes many issues:

Press Win + R, type services.msc and press Enter

Find "Windows Audio" in the list

Right-click → Restart

Do the same for "Windows Audio Endpoint Builder"

3. Run the Audio Troubleshooter

Windows has a built-in troubleshooter:

Go to Settings → System → Sound

Scroll down and click Troubleshoot

Follow the on-screen instructions

4. Update Audio Drivers

Outdated drivers are one of the most common causes:

Press Win + X → Device Manager

Expand "Sound, video and game controllers"

Right-click your device → Update driver

Choose "Search automatically"

5. Check Application Sound Settings

Some apps have their own volume controls. Check:

The Volume Mixer (right-click sound icon → Volume Mixer)

Audio settings within the app that has no sound

6. Reinstall Audio Driver

If updating didn't work, try reinstalling:

In Device Manager, right-click the audio device

Click Uninstall device

Restart your PC — Windows will automatically reinstall the driver

7. Check Physical Connections

If using external speakers or headphones:

Make sure the cable is firmly connected to the correct port

Try another USB or 3.5mm port

Test the headphones/speakers on another device to rule out hardware failure
