As the topic says: CALL IT OFFICIAL – win10 fucked things up! Everyone got the same issue. After last windows update microphone stopped working and none of your advices will help us. I suggest to rollback or uninstall all win updates and check it again. Unfortunately i have win10 home and I’m unable to uninstall updates (!!!! sic!!!). Anyway thank you for your effort. Have a nice day.
p.s. When in hit headset with my finger it’s possible to hear some sound…very quietly.
