Question About Sound Issue

[ToDDy720]

Hi there I'm new to the site and just wanted to ask a question about my sound issue.

I have a focusrite scarlet 2i2 with 2 krk rokit 5 speakers and make a very bad buzzing noise when in use with usb. I have tested with my laptop and no problem at all with the power in so doesn't seem like a ground issue. it is terrible when playing on graphic intensive games and still slightly buzzes with scrolling and general usage but nowhere near as bad as on games. this also happens with my astro a40 headset when connected with usb. I tried the headphone port at the back and no problems works fine just seems like a usb problem. I do have cheap adapters for my 24 pin motherboard which are braided which i'm thinking could be the case and also for my gpu. Any help is much appreciated thank you.

Did you use the same cable?

for the speakers and astro no they are both seperate cables. both work fine on laptop just on my pc it buzzes. the headphone jack on back works fine but anything that uses a usb for audio it buzzes badly. I did test without gpu and thats not the problem, All I can put it down to is power supply or motherboard or there is something else interfering with the usb. I'm gonna remove everything and see if it can be fixed.
