New PC front panel mic buzzing

[brinkor]

Hi, I've just ended up building my new little pc and then I run into a little problem.
I've realized that when I connect microphone to my front panel jack it is making very loud noise (buzzing) instead of transmiting my voice.

When plugged it to a rear panel everything is fine, so it's not faulty microphone.

I don't think I plugged something wrong either, because the hd audio connector goes in to the motherboard in only one way.
I've tried to detach and attache it few times as well as moving cables so it will not interfere with the rest but with no results.

Is my case (front panel) faulty?

My motherboard is: ASUS ROG STRIX B450-I GAMING

And case: Fractal Design Core 500

Everything is brand new so if it is faulty I can still return it.
Need some help, thank you in advance :)

Sounds like faulty wiring from the front panel. 

 

Time to bring the case back where you got it for repair or swap out.

I seen to have this problem aswell, but instead of my mic buzzing its my headphones buzzing right into my ears (quite annoying.) I figured out that if you have something plugged into the usb port right next to it it starts buzzing. Perhaps this is your issue aswell?

If you already tried moving the cable away from the power cables then the only other thing I can think of is faulty wiring.

 

If you're handy with a soldering iron you might be able to spot and fix the issue if it's on the from panel PCB but otherwise RMA is probably your best option.

 

As a last ditch effort to see what the problem is do you have any other chassis around with a HD Audio cable? Wire it in to see if the buzzing stops.

If yes. Bad case cables.

If no. Something with the motherboard is probably wrong.

Thanks for your answers guys.
I came to a friend of mine and tried connecting front panel from his case to my motherboard and guess what, microphone was still buzzing.
So I guess there is something wrong with motherboard.
After that I also tried returning my bios default settings as well as the whole bios update, but it gave no effect.

So I think returning motherboard to the seller is my only option now.
If you have any other ideas please let me know.

 

EDIT

I think I've just solved my problem.

I've decided to do one more thing before I send the motherboard back, so I've tested if my problem also occures in linux and, to my suprise, it doesn't.

I didn't think that this weird problem could be caused by bad drivers, but it probably was.
I've restored old drivers and installed the new ones from manufacturer site (previously I've updated these drivers through Driver Booster app) and my problem just disappeard.

Once again thanks for your help.
