Sound Mixer is missing from my settings - XBOX ONE

Hi, I'm hoping someone can assist. I have an original XBOX One and was looking to adjust the volume between my snapped apps and my main app. I found the instructions on the XBOX site as well as other places online, but when I follow these steps I am unable
to locate the Sound Mixer.

When I go to Settings > Display & Sound > Volume, I do not have the option for Sound Mixer but instead have the following:

- Chat Mixer

- Party Chat output

- Set Up TV & A/V Control

- Change Volume with Voice

I am running sound throught the TV speakers and have no other audio devices connected to the TV or XBOX, and after calling and speaking to an agent about the issue they were unable to confirm the cause of the issue, but suggested it could be caused since
there is not another audio device connected. I understand that could be a possibility but it also seems to make little sense that the Sound Mixer feature would be unavailable without an sound system of some sort installed.

Has anyone encountered this issue or have any ideas what may be the cause? Any advice is much appreciated. Thanks

:)

The only way to adjust the sound without any adjuster within the headphones itself is to change the sound mix by going into the settings itself within the Xbox One dashboard.

Alternatively if you are playing a game as the main app, just go to the game's audio settings and turn it down to 0.

This is what I do if I'm watching TV snapped.
