In game party chat loss and glitches

Noticed right away that when in a in-game party with friends, loss of audio during a match, we can't hear each other at all. Sometimes it comes back on its own, sometimes not until game is finished or we have to go back to lobby and restart the party. 

Similar issue when in-game party and playing, then if you get an Xbox Party invite, join the party, then leave, all communications ceased to exist. You can't hear your team in-game anymore. 

In the same situation above, when joining an xbox party, you can still hear the in-game party you left, but they can't hear you. 

Messing with the "In-world' Audio setting, it works for a few respawns then drops off entirely. 

50% of the time joining a match with a in-game party squad, the scoreboard is incorrect for example showing 960-0 and the loud end of game music is on the whole time, the theatrical suspense music that comes in before the end of game. We have to mute music audio during gameplay and ruins experience.
