How to Change the Default Sound Output Device in Windows 11 Audio Settings

Run the Playing Audio Troubleshooter

The Playing Audio troubleshooter is the quickest first check. It looks for common problems, such as a disabled device or a stopped audio service, and offers to fix them. It needs no manual configuration.

1. Press the Win+I to open Settings.
2. Select System from the left-hand menu.
3. Click Troubleshoot on the right side of the window. You should see a list of troubleshooting options.
4. Click Other troubleshooters.
5. Find Playing Audio and click the Run button next to it. Windows scans for audio devices and may ask which one is giving you trouble.
6. Follow the on-screen prompts and apply any fixes it recommends.

On some recent Windows 11 builds, this tool opens in the Get Help app instead of a classic troubleshooter window. The steps are the same: pick the device that has the problem and accept the suggested fix. If the tool reports nothing wrong, go on to the next check. Troubleshooter fixes can be reversed by changing the setting back in the Sound page.

Check Your Default Playback Device

Windows often sends sound to the wrong place. Typical culprits are a monitor with built-in speakers, a Bluetooth 🔷 headset that is switched off, or a docking station. Everything looks fine on screen, but nothing comes out of the speakers you are using. Check which output device Windows is actually using.

1. Press the Win+I to open Settings.
2. Select System, then click Sound.
3. Scroll down to the Output section. You should see a list of the playback devices Windows knows about.
4. Click the speaker, headphone or audio interface you want to use. Windows makes it the default output device, and a selected device is marked in the list.
5. Check that the volume slider is turned up and the device is not muted.

If your device is missing from the list, check that it is powered on and connected. Bluetooth 🔷 devices must also be paired and connected. You can also look under Advanced on the same page for All sound devices, where a disabled device can be turned back on. To undo this change, select your previous device in the same list.

Update or Reinstall Audio Drivers

Updating the driver, or removing it so Windows installs a clean copy, fixes many cases of “no sound”.

1. Right-click the Start button and select Device Manager. Approve the administrator prompt if one appears.
2. Click the arrow next to Sound, video and game controllers to expand the list.
3. Right-click your audio device, such as Realtek Audio or Intel High Definition Audio, and select Update driver.
4. Choose Search automatically for drivers and let Windows install any update it finds.
5. If Windows says the best driver is already installed, right-click the audio device again and select Uninstall device. Leave any option to delete the driver software unticked, so Windows can reuse the existing driver.
6. Restart your computer. Windows detects the missing device and reinstalls the driver at startup.

If a device shows a warning icon, the driver failed to load, which makes this step especially worth trying. Windows Update can also offer a newer audio driver under Advanced options and Optional updates.

Restart the Windows Audio Service

The Windows Audio service handles all sound in the background. If it freezes or stops, you get no sound even though the hardware and drivers are fine. Restarting it clears most temporary glitches and is safe to do. It does not change any settings.

1. Press the Windows key + R to open the Run dialog box.
2. Type services.msc and press Enter. The Services window opens. You need administrator rights to restart services, so approve the prompt if it appears.
3. Scroll down the list and find Windows Audio.
4. Right-click Windows Audio and select Restart. If Restart is greyed out because the service is stopped, select Start instead.
5. Right-click Windows Audio Endpoint Builder in the same list and select Restart. Windows may ask to restart dependent services, including Windows Audio. Click Yes.

Once the services show Running in the Status column, play a sound to test. Nothing needs to be undone afterwards.

Verify Cable Connections and Hardware Mutes

Sometimes the cause is physical and no software setting will fix it. Cables, switches and power buttons are quick to check, so look at them before changing anything else.

1. Check that your speaker or headphone jack is plugged firmly into the correct audio port. The line-out port is usually green. If you use USB audio, try a different USB port.
2. Look at your external speakers for a physical power switch, an LED power indicator and a manual volume knob. Turn the knob up.
3. If you use a gaming headset with an inline audio controller, check that its physical mute switch is off.

If you can, test the same speakers or headset on another device. If they stay silent there too, the problem is the hardware and not Windows.

Disable Audio Enhancements

On some hardware they cause distortion, conflicts or a complete loss of sound. Turning them off is a simple test, and you can reverse it at any time.

1. Open Settings and go to System › Sound.
2. Click More sound settings near the bottom of the page. The classic Sound control panel window opens.
3. On the Playback tab, right-click your default playback device and select Properties.
4. Go to the Enhancements tab, if it is shown, and tick Disable all enhancements.
5. Click Apply, then OK. If the properties window has a Spatial audio tab instead, make sure it is set to Off.

Which tabs you see depends on your audio driver, so the Enhancements tab may not appear on every PC. To undo the change, return to the same tab and untick Disable all enhancements.

What to do next

Once your audio works again, you can test your microphone input or set up spatial audio formats for gaming and media. If driver problems come back after a major Windows feature update, check your PC or motherboard manufacturer's website for a specialized audio driver package. These often work better than the generic driver Windows installs.
