I seem to be experiencing the same issue, I thought it was possibly just the modded server I've been playing in. Loaded an official server and happened instantly. Every discussion I've read on steam goes cold or gets zero response. I have almost 40hrs played with a total of maybe 15min of total game sound, I can speak to players but have to tell them to send a message in chat as reply. I'm using a HyperX Cloud Alpha S with 7.1 surround sound
