Weird buzzing on Roccat kave headset

[thankots]

Hello,

When I purchased the Roccat kave headset (analog 5.1 iwth a usb power supply) I realised that when I turn up the volume with the tuner (which is cabled to the headset) from 10% and up there is a weird buzz which lasts for 0.1 to 0.5 seconds and comes every 0.5 to 2 seconds. I've searched the internet and I believe it has something to do with the computer not grounding properly which I cannot realise why. What I'm asking is for a solution to this problem...

Try to disconnect them. Reconnect and see if there is any static. If so, try to get another computer and see if the same thing happens. If it happens on the other computer, you need an new headset.

EMI?

No, I've tried it on another computer and the problem is not there, I guess it has something to do with the grounding but what should I actually do next?
