Default Buzzing Sound while using Mic

Hello hwc.

After passing 5 hours troubleshoot my problem. I still didn't fix it. I come to you once again seeking wisdom and knowledge.

So here's the deal. Thanks to BF3, all the bugs of my pc are surfacing. When I'm in game and talking on vent. My friends hear a buzzing noise in the background. On my side. Perfect sound, for the output.

So I tried doing a campaign while having playback on (hearing yourself). I heard the buzzing. As soon as the game quit. The buzzing stopped. Notice I have an ASUS Xonar DX wound card (see sig for full system)

So here's what i have done.

1. Reinstall drivers (go in safe mode, use driver sweeper ... Etc). Same

2. Lower my sound card all the way at the bottom pcie. Nothing.

3. After some research. I removed my bracket from sound card and isolated it with tape. Nothing.

4. Took out my sound card and used the onboard, the buzzing was still present.

5. Took out my video card and isolated the motherboard heatsinks and pieces that I thought were touching the video card, nothing

6. Changed PSU PCIE connection, nothing

7. Removed video card bracket and ran it to see if it wasn't shorting

After a while, I ran Furmark... Instantly the sound was present. I also notice that a little bit of buzzing was coming out of my motherboard. It really looked like it was from my video card. I removed my VGA and ran Furmark, the sound was gone ( Didn't try my mic though... stupid me)

I have tried this solution too ... After some reading, forums started to point at a Coil Whine issue. I tried to change the settings of my card, I could hear the sound change a little bit. Still, it was present. It never went lower though.

I noticed something else too. If I shook the cable on my sound card and the volume and intensity of the buzzing would change. Also, taking off the screws on my video card (from the case) and moving it slightly would change the sound too !

Now I am really confused... I'm heading towards the PSU issue right now. BUT, it could be the video card too ! Now I'm off to bed ... this whole thing killed me.

EDIT: I have added a recording of the sound. This was while moving and looking around, in the first wagon (first level) in BF3

Thanks !

I just want to add again. Its only from microphone. As the speakers output the sound without buzzing on my side

I have a Sennheiser PC350. Even with the microphone muted it happens.

Does this only happen in BF3? If it does, try third party drivers: UNi Xonar brainbit | Unified Xonar Drivers

Otherwise the only other likely culprits are faulty ground and EMI from what you've described.

Then. Why would it sound perfect at any other moments except even the computer is under load. I'm even sure I can remove my mic and reproduce the sound

Tried those drivers. Still happenned... :(

Now to fix that EMI issue. Some have suggested me to ground my power supply to my case. I would have to get a wire and screw it to the case and PSU.

I was wondering. Can a PSU that gives not enough power cause a whining in the video card ? That's my next guess...

So even by removing the microphone, I can reproduce the sound.

Here what I tried today.

I removed the PSU from the case
I removed my motherboard and isolated the case with tape
Took out the sound card, tried it with onboard, still happens.

Strange, if I put pressure on the card (raising or lowering the card). I can make the sound go away. Maybe it's because of the PCI-E power connections...

So I'm confused right now. My next step is to try another PSU. If you guys have any suggestions, please post. As of this thread, I will keep it as a log, haha

Can you try the card in a different computer, or pci-e slot?
