Only party chat sound, no game sound

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today despite this MASIONGALEHOLDEN

This can be a bit dumb, but did you tried using a different HDMI cable?
Or connecting the console to a different HDMI port or TV?

In the meantime and if you didn’t tried this yet, please power cycle your console:
1. Turn off your console by pressing the Xbox button on the front of the console for about 10 seconds, until it shuts down completely.
2. Unplug the console's power cable from the console and from the power outlet. Wait 5 minutes.
Important: Be sure to wait at least 5 minutes. This step resets the power supply.
3. Plug the console power cable back in.
4. Press the Xbox button on your console to turn it on.

If you already tried all of the above, please tell me what else did you tried
In that way I can advise you different things or how to proceed

Hi Coorsl1te - game sounds do not route to the Xbox One Headset - it is used for Party Chat / Game Chat / Skype calls only.

I only get the party chat on my headset. I do not get any of the game sound on the headset

Edit on item #2

It's not meant to be "party chat" but "chat". Whether ingame or party. But the buttons are not switching between game or party chat, but to control the balance between game sounds and voice chat.

Hey

Thanks for the reply. Unfortunately any form of Xbox party is no good as we play with friends using ps4 hence the in game chat works great but the app doesn't seem to pick up in game chat only the game sounds.

I get if your in a party it overrides the in game chat but even when no party lobby is active it still doesn't come through yet works as it should via the headset so I know the sound is there

Its very odd! I can only assume maybe the in game chat is blocked by the app somehow although I'm hoping not
