Been having this issue forever now. Child's account on xbox will not allow him to use the mic in xbox party, even with friends. The only solution I've found at all, is to log in to the parent account on the xbox as well, then the mic will kick on for the child account. This causes issues though because I'm trying to use that parent account on pc gamepass, to play with my son on his xbox. I've gone through every parental and privacy setting, I'm certain everything is correct, I've even spent hours with xbox support with no solutions. Anyone ran into this issue and have any ideas of where to look to solve this?
