I have done this before as other forum topics suggested but nothing changed, i have my my headset the default device and have disabled every other device. For example i go into a server with my friend, first to see if the in game voip is working he talks first and yes i can hear him very well. Now when i talk my name pops up on the bottom left to show that im talking, but for him is as if i'm not even pressing the push to talk key. I have tried rebinding every key and still nothing.
