So recently Microsoft made me update to the new Windows build, #17134.48. Since then I've had no in-game VOIP funcationality at all. I've updated the appropriate drivers more than once since then as well, including just last night. I know they are up-to-date and if I'm using Discord my mic is working correctly, which leaves me to believe that the problem is not on my end but either a problem with BF1 & BF4 or maybe even Origin. I'm not sure what to do but it's really frustrating not being able to use VOIP to coordinate with my squad/friends.
