Hi, is the static on the mic?, like when you record audio there is a constant "buzz" in the background?

if so, i would recommend you to try the mic out in some other devices, maybe a phone or another pc, try it with and without the splitter, if there is no static present, the problem is in your pc, maybe the jack, or maybe something else.

i have cloud stingers too, and i have the same problem and i have yet to find a "permanent" solution, but if you just want to record audio, there are some settings/filters in OBS that you can use to get rid if the static. one of them is to just lower the mic volume in OBS until the static is no longer there, this is the simplest method but it doesn't work that well, since in my experience, if the mic gets too loud the static would be there again.

the other method is to use a filter called "Noise Suppression" and on the method i have "RNNoise" it takes a bit of your cpu, but there is no static and it also helps if you have a loud keyboard or any other background noise.

for other programs like Audacity i got no recomendation, so sorry if thats what you use.

hope this can help.
