When queing with friends i ahve no issue using full team communications, however anytime i solo queue i cannot voice chat and I am not even convinced text chat works. attached picture for summary.
This is an outstanding issue where you're using the "Character specific keybinds" option in the options menu. It probably breaks your pause button too.
just updating here since its an existing thread, i have figured out that if deadlock trys to access my mic and i am not actively using in another program, it completely breaks my mic until a restart happens
