Voice chat completely not working

I use bluetooth headphones as a headset and have checked every setting for voice chat in game my input  / output and switching every setting yet I can't hear anyone either in my lobby or in match no teammates nor anyone else given they were talking. I have had this exact issue also in the server slam and I  don't know how to fix it. I can hear the rest of the game just fine and the people can somehow hear me but I am not able to hear them. The upvote system is also bugged on this website. I could upvote my own post and then today I tried de upvoting and got into negatives and can't reset it to 0 it's now -1.
