How do I fix No output devices found in Windows 11?

Before we try the slightly more complex solutions here, let’s first do a few quick checks:

  • Why does my computer say no audio output device installed?

  • How do I fix No output devices found in Windows 11?

    1. Reinstall the audio driver
    1. Reset the audio controller
    1. Disable Driver Signature Enforcement
    1. Update the sound driver
    1. Change Mono audio settings
    1. Uninstall the last Windows Update

  • Restart the computer.

  • Update the computer to the latest version of the OS.

  • Make sure any third-party antivirus or firewall installed on the PC is disabled.

If these don’t work, these methods surely would.

1. Reinstall the audio driver

  • Press Windows + S to open the Search menu, enter Device Manager in the text field, and click on the relevant search result.
  • Double-click Sound, video, and game controllers to view the devices for that category.
  • Next, right-click your PC’s sound device, and select Uninstall device.
  • Click Uninstall in the confirmation prompt that appears.
  • Also, look for a device with SST in its name under System devices, and reinstall it too.
  • Once done, restart the computer, and Windows will automatically install the best driver for the device.

If no audio output device is installed, your primary approach should be to uninstall the driver for the affected device(s) and let Windows install the best one. It is especially helpful in the case of a corrupt driver, usually identified by a warning sign next to it.

If Windows doesn’t identify the device after the restart, go to the Action menu, and select Scan for hardware changes.

2. Reset the audio controller

If simply reinstalling the audio controller doesn’t work, you will have to reset the audio controller. To do that, first, uninstall the High Definition Audio Device from the Device Manager.

Once done, shut down the PC, remove the power cable, and then hold the power button for at least 60 seconds. After that, wait another 10 minutes or so, and restart the computer after plugging in the power cable.

This may seem trivial but it often does the tick when there is a problem with your audio device.

3. Disable Driver Signature Enforcement

  • Press Windows + R to open Run, type gpedit.msc in the text field, and hit Enter.
  • Now, double-click Administrative Templates under User Configuration, and then on System.
  • Select Driver Installation from the left, and then double-click on Code signing for driver packages.
  • Check the Enabled option, then from the When Windows detects a driver file without a digital signature dropdown menu, select Ignore, and finally click on OK to save the changes.

This is the quickest way, though you can also disable Driver Signature Enforcement after booting Windows in Recovery Mode. In case you are running the Home edition of Windows 11, you will have to manually install the Local Group Policy Editor.

Once done, check whether no output or input devices are found, or the issue is fixed.

4. Update the sound driver
