No Sound on Windows? Fix It Step by Step
No sound on Windows is usually a wrong output device, a muted app, or a driver problem, not broken speakers. Check these in order, from the simplest cause to the deeper ones, and test with a short sound after each step so you know which fix worked.
Follow these steps
- Check the right output device is selected. Click the speaker icon in the taskbar and check which device is selected for output. If sound is going to a monitor, a TV, or headphones you are not wearing, switch to the speakers you actually want to use.
- Check the volume and mute, including per-app volume. Make sure the main volume is up and not muted, then right-click the speaker icon, open Volume mixer, and check that the app you are using is not muted or turned down on its own. An app can be silent while everything else plays fine.
- Test with a different app and a different device. Play sound in another app, and if you can, try headphones or another speaker. If one app is silent but others play, the problem is in that app; if nothing plays anywhere, the problem is in Windows or the hardware.
- Run the audio troubleshooter. Open Settings, then System, then Sound, then Troubleshoot, or go to System, then Troubleshoot, then Other troubleshooters, and run Audio. It checks the output device, services, and common settings automatically.
- Update or reinstall the audio driver. Open Device Manager, expand Sound, video and game controllers, right-click your audio device, and choose Update driver. If that does not help, choose Uninstall device, restart the computer, and let Windows reinstall the driver.
- Restart the Windows Audio service. Open Services from the Start menu search, find Windows Audio, and restart it, then test sound again. If the service keeps stopping, note that, because it points to a driver or system problem rather than a volume setting.
- Check the physical connection. If you use external speakers or headphones, unplug and reconnect them firmly, try a different port if there is one, and check the cable for damage. A loose plug is a common cause that no setting can fix.
What NOT to do
- Turn the volume to maximum and keep testing. If the problem is the wrong output device, louder volume just sends sound to the wrong place more loudly.
- Download an audio driver from a random website. Use Windows Update, Device Manager, or the computer maker's official support page only.
- Reinstall Windows because the sound stopped. Driver and output-device checks solve most sound problems long before a reinstall is worth considering.
- Assume the speakers are broken after one silent app. Test another app and another device first, because app-specific mute is far more common.
If sound is back, play something for a full minute to make sure it stays back, not just for a second. If it still fails after a driver reinstall, note whether headphones work when speakers do not, because that narrows the problem to the speaker hardware.
