Volume Steps Setting (under Digital Assistants) not working

check the headset chat mixer in your audio settings also check the xbox general settings Go to your volume and audio out put in xbox settings and adjust your volume options in the chat mixer the party chat output and finally see what setting you have
under the headset audio. If you need assistance with this please come back and one of our volunteers will be able to assist your issue.

You can control the volume via Xbox App or through a virtual assistant such as Alexa. I use my Amazon Echo the most to change the volume.

Also, as for this tip:

"Other players cannot hear you

Make sure that the volume level is set correctly and that the volume is not muted in the Personal Settings area. To do this, follow these steps:

Press the Xbox Guide button on the Xbox 360 controller.

Scroll right to Settings.

Select Preferences.

Select Voice.

Make sure that the Mute option is not selected. To turn off the Mute option, select Mute, and then press the A button.

Increase the volume. To do this, select the volume bar, and then press the D-pad or the left stick."

I don't have this option "Mute" under the Voice menu...

Have you checked the in game volume controls under settings?

Hello Terrance,

Thanks for coming to the forums with your question. You will have to adjust the headset volume in the audio settings move it to the right for more volume in the headset. Also make sure your party chat output in volume settings under Display and sound is
set to headset.

Thanks,

Brad
