Actually that kinda helped. I couldn't hear anyone before game was too loud. I had to turn master volume up and then go into my computer's sound settings and turn game down and VivoxVoiceService up. Thanks for pointing me in the right direction.
I can't hear anyone ever, although I have tried messing with every sound setting in the game and on my computer sound controls. I don't know what else to do. I can hear the game just fine, but not VOIP.
