Fix No Audio Device Installed Error on Windows 11

The “No Audio Device Installed” error on Windows 11 means the operating system cannot detect or communicate with your sound card, speakers, or headset. The fix usually involves updating or reinstalling the audio driver, checking the physical connection, or restarting the Windows Audio service; start with the driver update method below, as it resolves the majority of cases.

What Causes the Error

Windows 11 shows this error in the Sound settings and often in Device Manager with a yellow triangle next to the audio controller. The underlying causes fall into a few common categories:

Outdated or corrupted drivers – after a Windows update, the audio driver may not be compatible or may have been overwritten.
Disabled hardware – the audio device can be turned off in Device Manager or in the BIOS/UEFI settings.
Windows Audio service stopped – the background service that manages sound can fail to start.
Physical connection issues – a loose cable, dead Bluetooth battery, or a faulty USB port.
Recent hardware changes – a newly installed graphics card or USB hub can conflict with the audio controller.

Step 1: Run the Built-In Audio Troubleshooter

Windows 11 includes an automated troubleshooter that can detect and fix common sound problems. It is worth running first because it takes less than a minute and may resolve the issue without manual driver work.

Open Settings (Win + I) and go to System > Troubleshoot > Other troubleshooters.
Find Audio in the list and click Run.
Follow the on-screen prompts. The tool will check for disabled devices, service issues, and driver problems.

If the troubleshooter reports nothing wrong but the error persists, move on to the driver steps.

Step 2: Update or Reinstall the Audio Driver

Driver problems are the most frequent cause of this error. Windows 11 manages most audio drivers automatically, but a failed update or a generic driver can leave the system without a working device.

Right-click the Start button and select Device Manager.
Expand Sound, video and game controllers.
Look for an entry with a yellow exclamation mark, or a device named High Definition Audio Device or Realtek Audio.
Right-click the audio device and choose Update driver.
Select Search automatically for drivers. If Windows finds nothing, choose Browse my computers for drivers > Let me pick from a list and try the High Definition Audio Device generic option.

If updating does not work, uninstall the device completely:

Right-click the audio device and select Uninstall device.
Check the box Attempt to remove the driver for this device if it appears.
Restart your PC. Windows will automatically reinstall the correct driver on boot.

For laptops and pre-built desktops, visit the manufacturer’s support website and download the latest audio driver for your exact model. Generic Windows drivers sometimes lack the special features (like headphone jack detection) that the manufacturer’s driver provides.

Step 3: Restart the Windows Audio Service

The Windows Audio service must be running for any sound device to work. If it crashed or was disabled, you will see the error even with a perfectly good driver installed.

Press Win + R, type services.msc, and press Enter.
Scroll down to Windows Audio.
Right-click it and select Restart. If the option is greyed out, first select Start.
Also check Windows Audio Endpoint Builder – it should be running as well. Restart it too if it is stopped.

To prevent this from happening again, double-click each service, set Startup type to Automatic, and click Apply.

Step 4: Check Physical Connections and BIOS Settings

Sometimes the problem is not software at all. Before going deeper, verify the basics:

If using USB speakers or a headset, try a different USB port, preferably one directly on the motherboard (not a front-panel hub).
If using a 3.5mm jack, make sure it is pushed all the way in. Some laptops have separate jacks for mic and headphones.
For Bluetooth devices, remove the device from Settings > Bluetooth & devices, put it in pairing mode, and re-add it.
Check that the volume is not muted and the output device in Settings > System > Sound is set to the correct device.

If none of that helps, the audio controller might be disabled in the firmware. Restart your PC and press the key to enter BIOS/UEFI (usually Del, F2, or F10 depending on the manufacturer). Look for an Onboard Audio or HD Audio setting under Advanced or Integrated Peripherals, and make sure it is set to Enabled.

Step 5: Use the Hardware and Devices Troubleshooter

Windows 11 also has a hidden troubleshooter that checks for hardware-level conflicts. It is not listed in the Settings app by default, but you can run it from the Run dialog.

Press Win + R, type msdt.exe -id DeviceDiagnostic, and press Enter.
Click Next and follow the prompts.
Restart the PC when it finishes.

This tool checks for issues like disabled devices, driver failures, and resource conflicts that the basic audio troubleshooter might miss.

Step 6: System Restore and Windows Update

If the error started after a recent change, rolling back or updating may fix it. Two options exist:

System Restore – search for “Create a restore point” in the Start menu, open the System Properties window, click System Restore, and pick a point from before the problem started. This does not affect your personal files, only system settings and drivers.
Windows Update – go to Settings > Windows Update and click Check for updates. Install any pending updates, especially driver updates labeled for your audio hardware.

If you recently installed a major Windows 11 feature update and the audio broke afterward, you can also go to Settings > Windows Update > Update history > Uninstall updates and remove the latest feature update to see if that restores sound.

Frequently Asked Questions

Why does my audio device show as “Not plugged in” even though it is connected?

This usually means the driver is working but the jack detection is failing. Try cleaning the port, using a different port, or updating the audio driver from the manufacturer’s website. On some laptops, the audio jack is a combined mic/headphone port, and using a headset with a single TRRS plug is required.

Can a Windows update cause this error permanently?

No, it is almost always a driver compatibility issue that can be fixed. If the problem persists after reinstalling drivers, check if the manufacturer has released a new driver for Windows 11. In rare cases, a faulty hardware component is the cause, but that is much less common than a software conflict.

Is it safe to delete the audio device from Device Manager?

Yes. Uninstalling a device from Device Manager only removes the software entry, not the hardware. Windows will reinstall the driver automatically on the next restart. If you also check the “Delete the driver software” box, you may need to reinstall the driver manually, but the device itself will not be harmed.

What if I have no “Sound, video and game controllers” section in Device Manager?

This means Windows does not see any audio hardware at all. Check the BIOS setting for onboard audio, verify the device is physically connected (for PCIe sound cards), and look under System devices or Other devices for an unrecognized controller. If nothing appears, the hardware may be faulty or disconnected.

Do I need to reinstall Windows to fix this?

Almost never. The error is almost always solvable with the steps above. Reinstalling Windows should be a last resort, and even then, it only helps if the problem is a corrupted system file. Try the driver reinstall and service restart first, as those resolve the vast majority of cases.

Why does my Bluetooth headset connect but produce no sound?

This is often a device selection issue, not a driver problem. Open Settings > System > Sound and make sure the headset is selected as the output device. Also check that the headset is not set to “Headset” mode (which uses the low-quality telephony profile) instead of “Music” or “Stereo” mode – this can be changed in the Bluetooth device settings.

General steps for current mainstream versions; menus can differ by device and version. See the disclaimer or report an error.
