why is my voice chat not working? :(

i can hear everyone else but toggling my own vc doesn't even show up. my inputs are correct, my mic works, i've switched my keybinds. idk if it's a bug or what, it worked for one game but now no matter how many times i relaunch i cannot get it to work. it's not that i don't hear anything when i ptt it's that it doesn't even show i'm speaking and no one can hear me
