Microphone Stopped Working on PC

[gtr2244]

 Asus Tuf z690 Gaming Plus wifi  motherboard. I'm out of ideas what to try to fix this. It was working fine, then started to get lower in volume and then nothing. I can't get any sound to record on the windows voice recorder, Steel Series Sonar equalizer it says I have a microphone attached but no sound for the testing, I've uninstalled the audio driver, reinstalled and tried Realtek audio, updated adio, gpu, bios, cleared cmos, changed the usb cable to my amp/dac. My headset is a Sennheiser Game One, I also purchased a cheap mic to test. Any more ideas would help.  Maybe it's something to do with the motherboard?

I can't actually find much info on this headset. Is it 3.5mm combo jack? Does it have two jacks? Is it just USB? Is the cable replaceable?
You mention a DAC, have you tested to make sure that is receiving audio? What make and model?
You purchased a cheap mic to test. I assume that also didn't work? Did you try plugging it into both the DAC and also into the onboard mic port for the mobo? And into the front panel IO mic port?

My Sennheiser Game One have a dual 3.5 plugs it is not replaceable, I use a Schiit Fulla amp/dac it has headset and mic ports, it was working fine. I've tried the cheap mic on all ports on my pc and the amp/dac.

I have both products mentioned here.  The game one does actually have a replaceable cable.  Have you tried plugging it directly into the motherboard?  My first guess would be the mic on the headphones or the cable, which trying it on the motherboard should answer that question.  The cheap mic was a good idea, but until you have verified that it even works on something, there is no saying what the issue is.  I would assume this is the problem before pointing the finger anywhere else.  Lastly if both the headset works onboard and the alternate microphone is confirmed to work on something else (so long as it's not USB) then I would figure it's the Schiit Fulla.  Nothing is perfect and products do fail, even quality ones.  *the gradual failure points to physical not software imo.

 I did try all ports on my pc, even on my Klipsch speakers. The cheap mic did work for a period on the desktop recorder.  Using my dac/amp. Then nothing, both won't work on any port, motherboard or the dac.
