how to use virtual audio cable audio repeater

for Spotify) to my Rode NT-USB (with Bose QCii connected via 3.5mm jack), there is no crackling whatsoever. Crackling only affects virtual audio devices like all channels from VAC or VBA. My physical USB and audio cables are not correlating to anything. I didn't find ANY solutions and I tried basically everything I found on the internet. Also, when there is no audio signal, there is no crackling. Not louder by the way, only more 'frequent' until there is only pure crackling left. When we don't do anything, it will eventually get so intense, that we can't even understand a single word anymore. The crackling will not stop nor will it get quieter or less intense on its own. when restarting the audio engine or changing buffer settings, the crackling stops for a few minutes before eventually starting again. But, the longer we wait, the more intense the crackling/popping noises get. Initially everything sounds clear and perfect. If anyone can shed some light on this issue what might be a good place to start looking for how to fix this because I used this before on a different PC and this setup worked fine and I've mirrored the configuration the best i could so I'm somewhat lost on the issue and i'm unsure if its some new quirk of OBS or a configuration issue in the Audio Cables.So, a friend of mine and I have a problem when using Virtual Audio Cable (VAC), VB Audio (VBA), Voicemeeter, etc. The issue is that for some reason when using either Kernal or MMS audio repeaters I'm able to hear all audio just fine from all lines, OBS on the other hand only hears line 2 and line 2 only.

This way i basically can monitor what the stream hears and i can just include or exclude certain audio when I want and just redirect 3 or 1 to my headset exclusively at any moment with a different repeater.

Repeaters basically go this way 3->2 and 1->2 and 2->My Headset. I recently upgraded my PC and finally got around to re-installing and reconfiguring my Virtual Audio Cables again for streaming.
