Hello,

I have an **MSI PRO-B760M-P DDR4** motherboard. After updating the BIOS to version **7E02v1E**, the **onboard Realtek audio device disappeared** from Windows completely. It is no longer visible in Device Manager — neither under sound devices nor under system devices (no "High Definition Audio Controller" either).

Here is what I’ve tried so far:

- I confirmed **HD Audio is Enabled** in the BIOS.
- Performed **CMOS reset** and loaded optimized defaults.
- Updated **Intel Chipset drivers** and **MEI** drivers from the official MSI site.
- Updated everything wit MSI Live Update.
- **Downgraded BIOS to version 7E02v1A** 7E02v1B,7E02v1D,7E02v1A,7E02v19 but still no onboard audio.
- ME FW is still the latest one (shows as newer, cannot downgrade manually).
- Reinstall latest realtek audio driver multiple times.
- Uninstall realtek audio driver by DDU.
- Enabling / Disabling HD Audio in bios settings.

Can you please help me
Thanks

We would like you to try the following method for Audio recovery
Make sure to flash back to the previous working BIOS first
This will be on your motherboard support page
The second-to-last bios released in 2023 will be the one you want

Once the BIOS recovers the audio, follow the steps below

Download the Svet tool and the latest BIOS, then update the BIOS with the Svet BIOS update tool.
This method has proven successful without the need for a patched BIOS to be used.

It says it's version 7E02v16, so is there no other option than to replace it?

If Audio is not working with that BIOS, it is beyond recovery by non-in-house methods

But I see it is working
See PM

First flash to BIOS
7E02v17
Verify that Realtek audio is showing in Device Manager

If so, Flash to the BIOS I provided

7E02v181

Verify the Realtech Audi device is showing in Device Manager
If it is, you can Flash to the latest BIOS
Do not downgrade from the BIOS I provide if Audio is displayed in the Device Manager

As long as the Realtech Audio is in Device Manager, it is just a case of getting drivers to Work.
This may be a different problem that needs a different approach to installing the Drivers.

Hi,

Thanks for the fix.

I was able to recover the audio after flashing BIOS version v16. However, when I update the BIOS again, the issue reappears. Do you to know why this happens or if there’s a solution for it, to have the last bios?

What board/current BIOS you have now?
EDIT: 1st flash back to 7E02v16
And check if the sound will be restored,
if yes, then reflash to the latest version 7E02v1G with >>Forum UEFI Shell Flash Tool<<

You solved my problem, I did as you suggested and the audio works! Thank you very much for your support. Now a new version of the BIOS has been released 7E02v1H1, can I use your utility to update it from 7E02v1G? Or do I have to use the MSI BIOS utility? Thank you very much!
