Headphones not playing game audio

Are you playing on a Xbox console?

If so, go to the audio settings in the console settings and set up the console audio to output game audio via headset.

In the headphone settings you can also set up spatial 3D audio, by turning the audio output for headphones to Windows Sonic, or if you have purchased the Atmos App (the free app only works 14 days with headphones), you can also set Dolby Atmos for headphones.

If you are on the PC, you need to make the headphone your device for audio output (not only voice communications).

Click on the speaker icon in the lower right, and choose the output channel for the headphone. Depending on your soundcard or USB headset, you need to select the proper audio output.

Once the headphones are connected, double-tap the guide button on the controller, and navigate to the bottom for headset settings.

You should find an adjustable headset volume setting. That will be the game volume in your headphones.

Please note that audio will still play from the TV even while headphones are connected to the controller. You can just mute your TV volume while using the headphones.

I love the audio in the game, especially when you play with headphones. There was something about that, mixed with the story, that just hooked me in and I enjoyed every minute of it.

On the Accessories app when I select Audio the levels have been altered. As i said to get decent audio from my headphones i need to have the controller audio and in game controller audio set to 100%. This suggests either an issue with the headphones [where
there was none before with regular xbox one controllers] or something with how the elite 2 handles audio. Can it be anything else?

Actually they are all pretty bad including my latest purchase, the Astro A40's. The Dolby Headphone audio processors included are fine. Its the headphones themselves that underperform vs even cheap models of "real" audio headphones.
