Headset/PC audio problem

[BaconPie]

So I started to notice this "bzzz"-ing sound in-game, does anyone knows what causes it? Headset is HyperX cloud, I tried it with another PC and its fine so I think the Cloud is fine.

This is a common problem (Just search the forum, tonnes of topics)

A buzz is usually EMI at the 50/60Hz range from the mains power.

 

It'll help to know your setup, how's it plugged into your PC (for example, try the backport andnot the front audio port)

what's the wiring in the PC like? (Lots of wires crossing eachother or not? Is the front panel cable crossing something else?)

Is the PC properly grounded? (Is the PC properly connected to Mains Earth, preventing ground loop?)

 

The cable should avoid other cables as much as possible to prevent interference from crossing over.

It's plugged in to the back, and th problem didn't occure since this day.The PC is new, about a month old and the motherboard is an MSI Z97 Gaming 5.I added in the creaming yesterday, whcich is the GTX 970 from also MSI, maybe it has something to do with it?

Now I tried the front audio port and it's working fine

That's especially weird, usually it's the other way around. I can't imagine a GPU emitting Humming in low frequencies, but it might be the extra added load increasing the strength of the interference.

If it's usually plugged in the back, does it come near the power cable?

I tried it again, only an issue when running BF3

It's not making contact with it, the PSU is bottom mounted.
