If you haven't, download the 5.2 update for mics. I have a blue yeti mic and I originally had this issue. I kept deleting and re downloading the game to see if it was just my PC or something, but it was because I just kept downloading the 5.1 and that's why. So download the 5.2 (0.5.2 mic test build) instead of the 5.1. Hope this helped!
