So I have this weird thing. From on day to the other, my teamchat isn’t working anymore. I have a push-to-talk button assigned on my mouse, and whenever I press that button I hear the ‘‘squeeky’’ sound you hear to notify you that people can hear you. Except, they can’t. I can’t hear them either nor can I see the player icons in the top left corner when they speak. i didn’t change a single setting, my mic is still working, so is hy headset, so I really don’t know where the problem is on this one.
Hi CaidaLibre,
Have you already tried re-assigning the keybind for push to talk to a different key?
