A:Answer Look for “in-game” audio settings. See if you need to change the chat function to “headset”. I am also assuming you have unplugged the mic piece and plugged it back in. You should feel it click solidly into place.
Also look in system settings for chat function. Depending on your age and the account permissions, there may be parental controls blocking chat.
If you are playing cross platform games such as COD Warzone, in game go to audio settings and turn off cross play chat, and turn it back on.
