Question Weird crackling and popping sounds

[Fuwlz]

Hi all, I hope I'm in the right category

I'm having this problem for a couple of months now, can't figure out what the problem is. I've deleted all audio drivers and reinstalled them but no succes. I mostly hear the popping/crackling when gaming, not so much listening to Youtube or Spotify.
I recorded this video to show you what I mean:

<- use headphones

As you can see/hear, it only happens when I click the right slider.

What I tried already:
Reinstalled all audio drivers (and tried without drivers)
Used a grounded outlet
Used a USB Headset
Used both audio outputs (directly in mobo and front of case)
Ran LatencyMon, but not sure how to read it, pics in bottom of post

PC specs that might matter:
CPU: Intel Core i7-7700K 4.2GHz Quad-Core Processor
Motherboard: Asus - STRIX Z270F GAMING
Power Supply: EVGA - SuperNOVA G3 650W 80+ Gold Certified
Headphones: Audio-Technica ATH-M50x

Do you have another known working mouse to try on your computer?

Or are you able to test your mouse on another known working computer?

Determine if the "sound effects" follow the mouse or stay with the computer.

You have almost zero latency according to that. Latency isn’t the issue

Did you ever find a solution by any chance? I have a USB headset as well and I have the exact same issue that you have. It has been driving me up a wall.....
