I had the same issue for a while, but for me, when i realize the sound isn’t there i close the game then open it again. It’ll put you back into the match and for me at least, that’s always fixed it! I’m on Xbox but i do hope this helps!
Terminus Voice lines are kinda depressing to be honest? Is it connected to the lore or something? Why did they feel the need to add that to his ultimate voice line
