No Audio output device is installed
Recently, I tried to update my windows (version 20H2) which was unsuccessful and I had this "No Audio output device is installed" with no sound on my laptop. I tried to update the windows again and it worked out fine.
Still, I have the same issue with my sound and running troubleshoot sound problems or reinstalling the audio driver doesn't work at all.
I have no hardware issue because I have no problem with ubuntu on the same system.
I searched a lot and all of them suggested uninstalling, reinstalling the audio driver which doesn't work.
Any suggestion is much appreciated.
Kind regards,
Ehsan

🔧 Step 1 — Restart into BIOS
You don’t need to change anything dangerous. We’re only looking for one setting.
- Restart your computer
- As soon as it begins booting, repeatedly tap the key that opens BIOS on your system:
- F2 or DEL are the most common
- Sometimes F10, F12, or ESC
If you’re unsure, try DEL first — it works on most desktops.
You’ll know you’re in BIOS when you see a blue or black settings screen.
🔍 Step 2 — Find the onboard audio setting
Every BIOS labels it slightly differently. Look for:
- Onboard Audio
- HD Audio
- Azalia Audio
- Realtek Audio
- Integrated Audio
- Audio Controller
It will be under one of these menus:
- Advanced
- Advanced → Onboard Devices
- Integrated Peripherals
- Chipset
What you’re looking for:
Make sure it is set to ENABLED.
If it’s disabled, that’s the entire reason Windows can’t see your audio hardware.
🔄 Step 3 — Save and restart
Once you confirm it’s enabled:
- Press F10 to save and exit
- Let Windows boot normally
- Check Device Manager again
If the audio controller reappears, everything else will fall into place automatically.
