How to Fix No Audio Device Installed in Windows 10 Easily

What causes “No Audio Output Device is installed”?

The “No Audio Output Device is installed” error in Windows 10 typically means your system cannot detect or use your audio hardware. Several factors can trigger this issue:

• Corrupted or Missing Audio Drivers: If your audio driver is outdated, missing, or corrupted, Windows 10 may fail to recognize your sound device.
• Disabled Audio Device in Windows Settings: Your audio device might be disabled in Sound Settings or Device Manager, preventing it from working.
