Static in Speakers When Motion on Screen

Hello!
I finally bought some speakers for my desk setup, while they sound great, I’m having some issues.

Current setup:
Computer to MOTU M2 (USB), to an ATOM Amp (RCA) that goes to my headphones (jack 1/4) and speakers (RCA). Heaphones are DT 1990 and speakers are Adam Audio T5Vs.

Problem is I’m hearing static through them at all time that I’m not hearing though my heaphones. The problem gets even worse when there’s motion on screen, like if I’m scrolling a website. Could this be a problem with my PSU (RM650x) or motherboard? Could it be a bad cable? I’m completely lost and can’t find anything on my issue. Any help is appreciated.

Sounds like a classic example of a GPU ground loop.

Try plugging audio equipment in the same or different outlets and see if it helps and if not try to isolate one component so for example your speakers into your interface or your amp or speakers to your Mobo lineout to see from where the ground loop could come.
If you can isolate it to one component than you can try some ground loop isolator or similar devices :wink:

It is likely electrical noise (= EMI) from the GPU making its way to the USB power rails.

Timestamped for those interested:

Do these devices lower the sound quality in the process?

Think some claim that filters can reduce the snappiness of the system but imo that should only be of a concern in the kilo buck range :sweat_smile:
For most mortals those filters for USB or the power plug help solve s problem and don’t have much if any negative impact on the sound
