I'm having this issue, it's 2024, I've been scouring the forums for the last 30mins and can't see if there was a fix for this. Just wondering if you know if there was any progress on this. Same thing here, mic works fine when I "test microphone" in the menu, but when I press C (which push to talk is bound to) while in a squad (or solo), nothing happens. Have tried it with other hotkeys and hasn't helped. Just wondering if you know if there was a post showing a solution to this?
