Due to the fact that I don't have a dedicated cockpit yet I use my computer desk for playing and since I have only one main pair of headphones for now it was very tiring to switch from one headphone jack to the other(I use an HDMI audio extractor to have a headphone option for my PS3) I decided to get my PS3 to be heard through my PC speakers to be able to chat with friends, listen to podcasts/music and play on my PS3 at the same time. So I use M/M 3.5mm cable that goes from HDMI audio extractor into a line-in on my motherboard's audio card, it then goes through Voicemeter software and into my headphones connected to my Behringer UM2. That was the explanation of the whole commutation.
Now for the problem: whenever I listen to line-in channel with GIMX adapter connected to the PS3, I hear electronic hum through it with some oscillations that appear to be USB signals being sent through the bus. I am almost 100% sure that GIMX adapter is causing this as when it's unplugged from the PS3, I only hear a faint normal combination of white noise and EM-interference if I amplify the sound enoough. I will try and record this sound for you to understand what I'm talking about. I didn't try this on my PS4 as I lended it to my friends for a couple of weeks (guys want to play Ghost of Tsushima and The Last of Us

Here's a link to the sound file with the noise: https://sndup.net/8szz
Solution: don't use crappy aux cables, spend $10-12 and buy a good thick cable with quality connectors, preferrably soldered by you or in-shop and not pre-made from a factory.
