Hi there,

I have an issue with my microphone not working for my new MSI B450 Gaming Pro Carbon AC.
Neither the front or real panel jacks are working.
The microphone seems to be way to quiet.
Even boosting it to +30db is still too quiet and introduces a sough.

So microphone is not usable at all in Windows itself and apps like TS3 and Discord.

I am using Windows 10 with Realtek HD Universal Driver Version 6.0.1.8642 / 2019-03-20 from

https://de.msi.com/Motherboard/support/B450-GAMING-PRO-CARBON-AC#down-driver&Win10%2064

Any ideas / suggestions how to fix this?

For now the only option seems like to returning the board...

Thank you in advance!

Hi,

Have you tested the mic on another motherboard or notebook?
Could you please try clearing the CMOS and reinstalling windows 10 (Do not install the Realtek audio driver for testing purpose at this point)?
Please use the "Voice recorder" app to test the mic.

Are you using the mic settings shown in the attached photos? 

Hope this helps

Hi LBJistherealchamp,

yes the microphone / headset worked perfectly on my previous mainboard and also works on my laptop.

I am also using the exact same microphone with the same settings shown in the screenshots.

I want to avoid reinstalling windows.
What would be the effect of clearing the CMOS? 

What about a bios update?

I am also wondering why there are two different audio drivers available here?

Hi,

Clearing the CMOS is going to reset the motherboard.

Doing a BIOS update might help and is worth a try.

If you do not wanna reinstall the OS, you could uninstall the Realtek Audio driver in safe mode.

Have you tried doing Windows 10 updates?

Installing the Realtek HD Universal driver is recommended when you are using Windows 10 RS3 or later versions and wanna use Nahimic 3.
If you only wanna use Nahimic 2 and your current OS is Win 10 RS2 or earlier versions, Realtek high definition audio driver is the one that you should install on your system.

Hope this helps
