My headset microphone all of a sudden doesn't work when i started using my new pc.

hey, so for some reason out of no where, when i try to speak in my headset the volume is really low, which is weird since back on my laptop it was perfectly loud and i could call and speak with no issues, i've checked all the audio settings on discord to make sure it is actually using the microphone, and it is its just so quiet that it doesnt pick up so i have to shove my mic down my throat for it to work. any advice?
