No longer have audio / Realtek is gone on my PC

Today, I logged on to my PC and I had NO AUDIO at all. I no longer have Realtek audio and nor can I install it.
My case is SUPER similar to this guys problem < https://answers.microsoft.com/en-us/windows/forum/all/no-longer-have-audio-realtek-is-gone-on-my-pc/c396088a-6196-4da6-8396-6fb4f71a155c?correlationid=f1bce827-f950-453a-b3a1-14acd09c6850&from=ContactUsWebBCQR >


1. Uninstalling the driver and restarting to make sure it downloads the generic driver
2. Trying to update the driver manually using the options listed ( didnt work made me bluescreen )
3. Downloading from Motherboards manufacturer's website. ( Gets OVERRITTEN by the HD AUDIO in safe mode and out. )
4. Reinstalling windows ( surprisingly shocked that it did not work )

Summarized - Realtek is gone from my PC, installing drivers from manufacturer's website will not work as it gets overwritten by HD Audio, I cannot reinstall as it won't work.

Hello, Daniel

Welcome to Microsoft Community.

It sounds like the Realtek driver being overwritten by HD Audio might be caused by Windows Update automatically installing an incompatible driver. To prevent the system from overwriting your correct driver, you should disable automatic driver updates. Just search for "Change device installation settings" in the Start menu, select "No," save the changes, and then restart your device.

Regarding the blue screen issue after manually installing the driver, that could be due to an incompatible or corrupted driver version. Try using a tool like Display Driver Uninstaller (DDU) to completely uninstall the existing driver in Windows Safe Mode. Then, download and reinstall the driver from your motherboard manufacturer's official website. Make sure you get the right version for your operating system.

If the driver is still being overwritten even in Safe Mode, you might need to temporarily disable driver signature enforcement to install an unsigned driver. Here's how:

  1. First, disable Secure Boot in your BIOS, as it prevents unsigned drivers from loading.

  2. Enter cmd. In the search results, find "Command Prompt" and select "Run as administrator."

  3. In the Command Prompt, enter the following command and press Enter:

    bcdedit /set nointegritychecks on

  4. Restart your computer.

To re-enable driver signature enforcement, use this command:

bcdedit /set nointegritychecks off

And restart your computer again.

If you're still having problems after all that, it's likely a hardware issue. You should contact the manufacturer's customer support for assistance.
