I can not fully connect to party chat. I can hear my friends but they can't hear me. I have tried to troubleshoot but that didn't work. Never had this issue until this xbox preview came out what can I do??
I'm not in the preview myself but have you checked the preview forums to see if others are experiencing the same problem?
My suggestion to anyone, whether in the preview or not would be to run a network test to see what NAT type you have.
Also a hard reset to see if that solves it.
Hopefully someone else will be able to help you out if the above doesn't help.
Good luck :)
