Realtek Audio not working after Bios update

[arunkumar78]

I updated my PRO B660M-A DDR4 bios from 7D43v1E to 7D43v1F through MSI control center, after that Realtek Audio is not detecting/showing in Windows 11 and Windows 10 dual boot OS. The Audio is enabled in Bios.

Hi, i have MSI b660m-a motherboard, same problem with REALTEK audio when i update the bios. Please help me :-D

Audio is still not working with 7D43v1H released in April 02. How can such a critical bug still remain unfixed after so many months?! Very disappointing from MSI
And I don't wanna hear about beta BIOS. This issue should not be there in the first place in "stable" BIOS. I don't want to flash some unstable beta firmware to my board.

I don't want to flash some unstable beta firmware to my board.

It is not an unstable Beta Bios but one with a patch for the Bug that is affecting some boards
So far the Bios sent to end users have Fixed over 99% of affected Boards

Hi, I ran into this issue as well. With a MSI pro B660-M A DDR4, I upgraded from 7D43v1E to 7D43v1H and lost audio. Then I downgraded to 7D43v1G and it still wasn't working. I will downgrade back to 7D43v1E now...

Exact same issue with my B660M-A WiFI board.

Affected BIOS's 7D43vAF, 7D43vAG.
Rolled back to 7D43vAE and my Realtek Audio controller is working again. BUT... I have a strange unresponsive video port issue that happens after power controls turn off my monitors. This started me on the BIOS update journey only to find that the updates kill my audio.

No Bueno! Please Fix!
