I am muted whenever i play matchmaking with people, but if i invite them to the party they can hear me. They have the capability of unmuting me but usually people just dont. Why am i muted to everyone and why are some people muted to me (i always unmute) i want this mute to be removed because i like to be able to hear and communicate with peaople i play with. Please help me 
What you are experiencing as a voice ban. People must have reported you for things you have said in game (or just done it for fun) therefore you will be muted to anyone who is in your game unless they choose to unmute you. It will be the opposite for people you have to unmute (they will have been reported).
