I've tried my best at trying to figure out where the buzzing sound originates from and I'm a little stumped and not sure what to try/check next. I've read a bunch of forums before posting this but I couldn't find any information on what to do next.
But as you can see in this video View: https://imgur.com/a/NQwzzI3
I then noticed that I can make the "noise" sound a lot higher by pulling the headphone cable when connected and even make the buzzing sound disappear completely.
I believe that it might be a ground issue? I think that when I move the cable I make some of the components in the PCB touch the metal plating where the PCB is mounted on and it's then picked up by the audio jack. I'm not well educated in electricity and not sure how to check/confirm if this is true. I would like to try and lift off the PCB with the metal plating from the chassi but I'm afraid it could cause a short? I have a multimeter but not sure how to use it for this. So if anyone here could give me any advice I would really appreciate it.

- So far I've concluded that the buzzing sound only comes from the front headphone jack when the GPU is under load, i.e. when playing Apex. If I plug my headphones on the backside directly to the MB I won't get any buzzing sound at all.
- Realtek drivers are updated to the newest version from MSI website but nothing changed.
- I tried rerouting the audio cable from the MB to the front panel via the "left side" so that it was as far away from any other cable as possible without any change.
- I've disconnected both of the USB cables from the MB and front panel to conclude that it is not a USB ground issue.
