Your situation sounds frustrating, but it's good to know the hardware itself is functioning since Ubuntu runs fine. The "No Audio output device is installed" issue after Windows updates is a common problem and can stem from driver or system configuration issues.

Since Ubuntu works fine, hardware is likely intact. The issue is with Windows configuration or driver corruption. If none of these steps work, consider performing a repair install of Windows 10 as a last resort.

🔧 Step 1 — Restart into BIOS

You don’t need to change anything dangerous. We’re only looking for one setting.

1. Restart your computer
2. 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.
