I know a lot of people are having problems hearing or talking with others in a game lobby, to fix this you have to hard reset your xbox 1. To hard reset you have to pull the power plug and leave it be for about a minute, then hook it back up, fire up your xbox 1 and if everything went good you will be able to communicate with others again ...
Now this doesn't work for everyone but it has worked for me every single time ..
We need to stop going into private chat parties when we are playing you guys, it's not good for recruiting and it brings more problems like getting your IP seen by assholes who want to IP flood you, slow down of gameplay ...
