Why am I unable to hear party members when I am in a chat?

I have figured out the issue. For some reason when I have the option set to channel sound through both the headset and TV it really mutes the sound going to the headset for some reason. When I switch to headset only for party chat it instantly triples or quadruples the sound entering the headset. Not sure why but I am unable to allow my girlfriend to listen to my party chat while I play (it's less boring for her to watch when she can hear the people I'm playing with also).

The auto off is designed to help save battery life. The charger cable prevents it from shutting off, at the cost of a REALLY annoying buzzing sound. Sometimes your party members can hear it, sometimes not, and the volume seems to be random. Also, I've noticed
that if I am in a private chat with one person, my controller will not shut off...I am not sure why. It stays on for hours and hours in a private chat, but in parties it shuts off after about 10 min of inactivity.

It is for every game, When I am in a party and I go to game chat it does not work when I am not even in a party it does not work and for Overwatch it tells you when you are in game chat and yet I still can not hear or talk to anyone although it will show
when others are talking.

I am experiencing a similar issue. Could not chat with friends in party chat, but when I left, I could talk to and hear everyone in Battlefield.

I am having this same exact issue. I have forwarded all the required ports for both Xbox and call of duty. I am able to talk to PS4 players in game chat but rarely xbox players. Party chat works fine for xbox but then am unable to hear PS4. Is there anything
else we can check? I believe this issue may be related to the recent game update.
