How to Fix Sound Not Working on Windows 11

Learning how to fix sound not working on Windows 11 usually takes less time than you expect, because most sound problems have a simple cause. One day your speakers work fine, and the next day a video plays silently, a video call has no audio, or your headphones are not recognized at all. The cause is often something small: the wrong output device is selected, the volume is muted in one place you did not check, a driver updated badly, or a setting changed after a Windows update. In this guide, you will work through the fixes in order, from the quick checks that solve most problems in a minute to the deeper driver and service fixes that solve the rest. Follow the steps in order, and test your sound after each one, so you know which fix worked.
Start with the Quick Checks
Before you change any settings, check the obvious things, because they cause most sound problems. First, check the volume. Click the speaker icon in the taskbar and make sure the volume is turned up and not muted. Then check the volume in the app you are using, such as the video player or the video call, because Windows volume and app volume are separate. Second, check that your speakers or headphones are actually connected. A loose headphone jack, a USB cable that is not fully plugged in, or a Bluetooth device that is turned off will all produce silence. Unplug the device and plug it back in, and if you use Bluetooth headphones, make sure they are charged and connected. Third, check that the right output device is selected. Click the speaker icon, then click the small arrow next to the volume slider, and you will see a list of output devices. Choose the one you want to hear sound from, such as your speakers or your headphones. Windows sometimes switches to the wrong device on its own, especially after you plug in a monitor with speakers or connect a Bluetooth device, and this one click fixes a large share of no-sound problems. If you use Bluetooth headphones, our guide to connecting Bluetooth devices to Windows 11 can help you pair them properly. Finally, test with a different app and a different file. If YouTube is silent but a local music file plays, the problem is in the browser or the website, not in Windows.
Run the Windows Audio Troubleshooter
If the quick checks did not help, let Windows try to find the problem itself. The built-in audio troubleshooter checks your output device, your drivers, and your audio services, and it can fix common problems automatically. To run it, open Settings, go to System, then Sound, and scroll down to the Advanced section, where you will find Troubleshoot common sound problems. Click Output devices, choose the device that is not working, and let the troubleshooter run. It will test the device, check for driver problems, and suggest fixes. Follow any steps it offers, and restart your computer if it asks you to. The troubleshooter is not perfect, and it will not fix every problem, but it catches a surprising number of them, including a muted device, a disabled device, and a driver that needs attention. It is also a useful diagnostic step: if the troubleshooter says it cannot find a problem, you know the issue is more likely to be a driver or a service, which are the next sections in this guide. If the troubleshooter does find a problem and fixes it, test your sound right away to confirm it is working before you move on.
Check Your Sound Settings in Depth
If the troubleshooter did not solve it, open the Sound settings and check them carefully. Go to Settings, then System, then Sound, and look at the Output section. Make sure the correct device is selected, and click the arrow next to it to open its properties. Check that the volume is up, that the device is not disabled, and that the audio format is set to something standard, such as 24-bit, 48000 Hz. A format that your device does not support can cause silence, and changing it to a standard format often helps. Next, look at the volume mixer. Click the speaker icon, open the volume mixer, and check that the app you are using is not muted or turned down there. Windows remembers volume levels for each app, so an app you muted weeks ago can still be silent while everything else works. Also check the Sound settings for exclusive mode, which lets one app take full control of your audio device. If a program has taken exclusive control and then crashed, it can block sound for everything else. Turning off exclusive mode in the device properties can fix that. Finally, check whether Windows is sending sound to the wrong place because of an app-specific setting. In the Advanced sound options, each app can have its own output device, and an app set to the wrong device will be silent even when the system output is correct.
Update or Reinstall Your Audio Drivers
Drivers are the software that lets Windows talk to your sound hardware, and a bad driver is one of the most common causes of no sound, especially after a Windows update. To check your drivers, right-click the Start button and open Device Manager. Expand the Sound, video and game controllers section, right-click your audio device, and choose Update driver, then choose Search automatically for drivers. If Windows finds a newer driver, install it and restart your computer. If the problem started right after an update, the new driver may be the problem, and rolling back can help. In Device Manager, right-click the audio device, choose Properties, go to the Driver tab, and click Roll Back Driver if that option is available. If updating and rolling back do not help, try uninstalling the driver completely. Right-click the device, choose Uninstall device, and restart your computer. Windows will detect the sound hardware when it starts up again and install a fresh driver automatically. You can also visit your computer or motherboard maker’s website and download the latest audio driver from there, which is often newer than the one Windows finds on its own. Avoid driver updater programs that promise to fix all your drivers at once, because they often install the wrong drivers and add unwanted software. Stick to Windows Update and the manufacturer’s official website, and test your sound after each driver change.
Restart the Windows Audio Services
Windows uses background services to handle sound, and if one of those services stops working, you get silence even though everything else looks correct. Restarting them is quick and safe. Press Windows + R, type services.msc, and press Enter to open the Services window. Find Windows Audio in the list, right-click it, and choose Restart. Then find Windows Audio Endpoint Builder and restart it the same way. While you are there, double-click Windows Audio and make sure its Startup type is set to Automatic, so it starts every time Windows does. If a service will not start, or if it stops again right away, that can point to a deeper problem with a driver or with Windows itself, and the driver steps in the previous section are the next thing to try. You can also restart your computer, which restarts all the services at once and fixes many temporary glitches. A restart is the simplest fix in this guide, and it is worth trying early, not just as a last resort. If sound works after a restart but stops again later, note what you were doing when it stopped, because a particular app or device may be triggering the problem.

When the Problem Is Hardware, Not Windows
Sometimes the problem is not software at all. Test your speakers or headphones on another device, such as a phone or another computer. If they are silent there too, the device itself is broken, and no Windows setting will fix it. If they work on another device, try a different port or cable on your computer. A worn headphone jack, a damaged USB port, or a failing cable can all cause sound to cut out or disappear. For desktop computers, try the audio jacks on the back of the computer instead of the front, because the front jacks are connected by a cable that can come loose. For laptops, try both the built-in speakers and headphones: if the speakers work but headphones do not, the headphone jack is the likely problem, and if neither works, the problem is more likely to be software. Also check for physical damage, such as a bent headphone plug or a cable that only works when you hold it at an angle. If you use external speakers, make sure they are plugged into power and turned on, and that their own volume knob is turned up. It sounds obvious, but powered speakers that are switched off are a common cause of a silent computer. If you have tried every software fix and the hardware works on another device, the next step is a repair shop, because the sound chip or the audio jack on the computer itself may have failed.
Conclusion
Now you know how to fix sound not working on Windows 11, step by step. Most problems are solved by the quick checks: the right output device, the volume turned up, and a properly connected device. The next most common fixes are the audio troubleshooter, the sound settings, and a driver update or reinstall, followed by restarting the audio services. Work through the steps in order, test after each one, and you will find the cause without wasting time on fixes you do not need. If the problem turns out to be hardware, testing your speakers or headphones on another device will tell you quickly. Keep this guide bookmarked, because sound problems have a habit of returning after an update, and next time you will know exactly where to start.
