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 Guys!

I raised a ticket with the MSI support team, they asked me to clear the CMOS, disable the audio, save bios, and restart. Again enable the audio. That did not work, it was like the Realtek audio controller itself was not there.

I informed MSI that this issue is faced by others too and MSI needs to release a BIOS fix ASAP.

So I just downgraded my BIOS back to 7D43v1E using M-Flash. Now the Realtek audio is recognized in the Device Manager. I updated the Windows 11 audio driver, it is working fine. I can't use my PC without audio.

All of you were very helpful, Thanks 🙏

How do you do this? Tried to download older Bios but it said not available?

That's an AMD-based board. This thread is about problems with the latest BIOS on Intel-based boards.
So i assume you have a totally different problem than those from the thread here.

If it's just that you can't get Windows installed, proceed as mentioned here (including BIOS update). And once you're in Windows, instead of the Intel-specific drivers from that thread, you want to install the AMD chipset drivers from here, and whatever MSI drivers you need from their support page.

Again the BIOS update explained in more detail:
1) Get the latest BIOS. It's the topmost one on the MSI support page for your board.
2) Extract the file and you will get a text file and the BIOS file. Put the BIOS file into the root folder of a USB stick/drive.
3) Enter the BIOS by pressing DEL during boot, go to "M-FLASH" in the BIOS.
4) Once M-Flash (the updater) is loaded, it will show a list of your drives. Select the USB stick and select the previously extracted BIOS file on there.
5) It will ask for confirmation and then update the BIOS. It's fully automatic from there, takes about two minutes.

You never described your problem before, i don't think? What is it? Tell you what, create a new thread in the AMD section, list all (!) your hardware, and describe exactly what problems you have. Then we can think of a solution to it. This is the wrong thread for it.

Same pb with MSI PRO B760-P DDR4 II with 13600KF
but the 2 available BIOS (12 and 13) are not working for audio (realtek not detected by W11). I need to use NVIDIA controller to get audio through the monitor!

Still no BIOS update. This is frustrating. My MSI Pro B660M-A is now still on 7D43v1E. Good thing my newly installed 14700K works fine.

Same motherboard, same bios update and same problem. I uninstalled the display and sound drivers with DDU and reinstalled them but it didn't work. I installed the old bios (7D43v1E) version and the problem was solved.
However, Realtek Audio Console still did not work at first start-up and gave an error, so I reinstalled the audio drivers again. Now everything is normal again.

17:21 Me My product is:
MSI PRO B660M-A
17:21 Me HD Audio not working after BIOS update 7D43v1F.
I already cleared CMOS, disabled HD Audio, restarted, re-enabled HD Audio, and it's still not working.
I re-flashed 7D43v1E and it works again.
Will not update to latest bios until you fix it.
All B660M-A owners are facing the same issue, check the forums.
17:22 Msi Agent Hi! welcome to MSI chat! we appreciate your business. Please give me some time to read your concern and pull up my resources to help you. Kindly stay on the line. Do not switch tabs as the chat may get disconnected. Thank you!
17:23 Msi Agent Hi Elijah, we're sorry to know about the problem.
17:23 Msi Agent Let me assist you.
17:23 Me Here are the complaints in the official MSI forum. All of us are facing the same problem with B660, B660M, B760 motherboards.
17:23 Msi Agent So on the latest BIOS update from the website. It has an issue when it comes to Audio.
17:24 Me Yes.
17:25 Msi Agent Just to confirm right now your board is running perfectly to version 7D43v1E right?
17:26 Me Audio is perfectly working on 7D43v1E, but Intel APO cannot be enabled on my 14700K
17:27 Me So I need 7D43v1F, but audio is not working. I need both Intel APO feature and Realtek Audio coming from the motherboard. It's been almost 1 month since the BIOS update 7D43v1F was released.
17:27 Msi Agent I see, thank you for information us about that. We will coordinate this with our software engineers to check this 2 BIOS version and to check when they will release new BIOS update.
17:30 Msi Agent Is it alright if we will send you update via email about it?
17:31 Msi Agent I will escalate this with our software engineers to check on this update and ask when the next BIOS version will be release.

Downgraded BIOS to previous version, like suggested. That fixed HD audio controller and i can use speakers again. I was really stressed that audio controller in MB got broken or something. Hopefully they release new bios soon with the hotfix.

PRO H610M-E DDR4

Same here, everything worked fine with BIOS 7D48vAC , then I updated to 7D48vAD.

With the 7D48vAD version, no sound, all Realtek devices disappeared from Device Manager, and reinstalling the Realtek HD Universal Driver didn't help either.

After downgrading to 7D48vAC , Realtek devices reappeared in Device Manager and everything worked again.

Same Mb as me. I thought I was going crazy updating uninstalling reinstalling msi realtek audio trying to get realtek to come back to device manager and sound settings after flashing to AD. Like yourself a rollback reverted all back to normal.
