No Audio Output Device Installed Error on Windows 11

Drivers act as bridges between your hardware and operating system. Outdated, corrupted, or missing audio drivers are a primary cause of this error. Windows updates or third-party software changes can sometimes disrupt driver functionality.

Physical issues, such as a disconnected speaker or headphone jack, faulty audio hardware, or conflicts with external devices (e.g., USB headsets), can trick Windows into detecting no audio output device.

While updates aim to improve system performance, they can occasionally introduce bugs. An incomplete or incompatible update might disable audio drivers or settings.

Sometimes, the audio output device is manually disabled in Windows settings or via third-party apps, causing the system to overlook it.

In rare cases, the motherboard’s audio controller might be disabled in the BIOS/UEFI settings, preventing Windows from recognizing the hardware.

1. Step 1: Check Physical Connections
   • Ensure speakers, headphones, or external audio devices are properly connected.
   • Test the device on another computer to rule out hardware failure.
2. Step 2: Update or Reinstall Audio Drivers
   1. Press Win + X and open Device Manager.
   2. Expand the Sound, video, and game controllers section.
   3. Right-click your audio device (e.g., Realtek High Definition Audio) and select Update driver.
   4. Choose Search automatically for drivers and let Windows install updates.
   5. If the issue persists, right-click the device again and select Uninstall device. Restart your PC to trigger automatic driver reinstallation.
3. Step 3: Run the Audio Troubleshooter

5. Step 5: Check Windows Updates
   1. Navigate to Settings > Windows Update.
   2. Click Check for updates and install any pending updates. Restart your PC afterward.
6. Step 6: Roll Back Drivers (If Updated Recently)
   1. In Device Manager, right-click your audio device and select Properties.
   2. Go to the Driver tab and click Roll Back Driver if the option is available.
7. Step 7: Verify BIOS/UEFI Settings
   1. Restart your PC and enter BIOS/UEFI (usually by pressing F2, Del, or Esc during startup).
   2. Locate the audio controller settings (often under Advanced or Integrated Peripherals).
   3. Ensure the audio device is Enabled. Save changes and exit.
8. Step 8: Perform a System Restore

   If the error started after a recent change:
