This is probably really easy to fix, I don't play much on live, so please don't laugh 
When I am playing team deathmatch and in a party, I can only hear the people who are on My Friends list, I confirmed this by adding someone to my friends list that was in the party, this enabled me to hear them. Is there a setting that I have inadvertently set so I can only hear people on my friends list?
Hope this male sense, Ideally I want to hear everyone on my team regardless if they are in my party or on my friends list.
