Loud rumble/static sound from microphone when cpu/gpu are under slight load.

Hi there,

Today I purchased a USB headset/mic. The headset is great but the microphone has an odd problem. Headset name: Corsair HS40

On desktop, where the cpu/gpu load is low. The microphone is perfect. No problems. But if I run an game such a Battlefield 4. The microphone seems to emit a strange rumble/static sound. The sound is only there when running intensive programs such as a game. So I think the problem occurs when the CPU or GPU is under load. But why would that effect the microphone?

Things I have Tried

Updating drivers
Disabling on-board sound card.
Disabling gpu sound card.
Using different USB ports
Installing other sound drivers such as Realtek HD Audio Driver
Un-plugging audio jacks from motherboard.


I not sure if it is a kind of interference, the headset has its own Sound card. So is no where near the other components the computer.

I have recorded the sound that the microphone makes, I did this by using listen to device in the Audio settings. Sound: https://www.youtube.com/watch?v=7hhZ3kao0Jg

I also thought it might be somthing to do with the computer being ground/or not. But the fact that the sound isn't there all the time made me think otherwise.

I hope you can hope, I've been trying to fix this for the last 7 hours! :(

Thanks if you can.

  1. honestly based on what is going on, it sounds like the problem is with the sound card on the mike itself. just return it

    I've just tried the headset on a laptop. and there were no such problems. So I don't think its the headsets soundcard.

    Any other ideas?
