I had issues with my mic on the xbox app on pc, but not on discord and such. so i looked up some tutorials and swiched advanced microphone format from 44100 HZ (cd quality) to 192000 HZ (studio quality) and then my mic seemed to be fixed. but then i booted CSGO up and now my microphone is super loud, sensitive and grainy. it picks up every sound and breath and i cant seem to fix it. i also tried switching to earplugs but they have the same problem now.
