Hey! This is a bit of a doozy, I wanna go into detail here so it might be a little long, thanks for sticking with me!

A couple days ago my microphone stopped working, I thought it wasn't that odd, since it was a cheap little thing from Amazon, it was a little microphone that was attached to the cable connecting to my headphones. Then I used a splitter to separate it into mic and headphones. I had a couple weird issues with audio loop-back. I assumed this was because of my open-back headphones, therefor it's simply the sound leaking out, but that wasn't the case. I don't remember how I fixed that. When the microphone stopped working I assumed it was the splitter, maybe it had caused the loop-back issues? I ordered a new splitter, but, it didn't solve the issue.

My next idea was that the microphone itself was broken. I ordered a new microphone on Amazon. Again, turns out, the microphone wasn't the issue.
Around the time my audio broke I installed a new audio program? Maybe that's what caused it? I removed the app, reset my Realtek drivers, but nothing worked, I assumed that it must've changed something deep in my system settings that, for one reason or another broke my audio. Before doing anything dangerous to my system I decided to try the microphone on my dad's Windows 10 laptop, and it worked fine! So I assumed the issue was because of the software, I ended up resetting my windows (keep personal files, but basically remove and reset everything else), but again, it didn't fix it.
Today I installed Ubuntu on a flash drive and tested it on there, the microphone had the exact same issue.

Working with all that info, I can only conclude that there's some kind of issue with the microphone and my motherboard. I've tried it in multiple different ports and it still doesn't work. The one thing that stumps me is that my headphones have been working throughout all of these issues.

One more thing, the audio I do pick up from the microphone differs a lot, but there's always some kind of static. I read that this might be due to a short circuit in one of the audio jacks? But, this issue occurs on all of the audio jacks, and when I switch the cables around, my headphones work just fine. Maybe there's a short inside of the sound card?

Is there any precedent for this happening? Can I swap out just the audio module or should I buy a new board entirely (forgot to mention, current one is an Aorus b550 elite v2 revision 1.0)? Maybe I'll just use an external sound card instead?

If anyone can give me some words of wisdom on this I'd greatly appreciate it. Thank you very very much.
 
Can you post a link of the splitter you bought. I have a hunch but I need to see the splitter to validate my hunch or disregard it as the issue.
I'm not using the splitter anymore, I got a new microphone which is completely separate from my headphones. The original splitter came with the microphone, then I ordered a new one, form UGREEN, a reputable brand, and it still didn't work, that's when I bought a new microphone.
 
The microphone is TSSR. But again, the port or jack cannot be the issue, if I switch which ports my headphones and microphone are plugged into, my headset still works, microphone doesn't. I have 6 total 3.5mm ports on my computer, I've tried all of them with the microphone, none work. The headphones do. The microphone works on other devices. This is not the issue.

Just get a discrete sound card (internal, not external).
There's no need to replace motherboard for this.
