Volume slider on menu doesn’t do anything.

The Volume + and - raises and lowers ALL volume. The Game and Chat buttons adjust the mix between the two. That means, repeatedly press the Game button to raise the Game volume, in relation to chat. Press the chat button repeatedly to raise the chat volume.
This is completely independent of the volume.

This of it like a mixing board. You have a slider for the Game track, a slider for the Chat track, and a Master volume slider.

It could be that the volume slider on the guide is on the game and not the party

If you have an Xbox headset, there is a microphone and volume button on the wire. You could have this switched off. You want to put the slider thing to the microphone symbol with no line through.

If this doesn’t work use this link.

Hope this helps have a good evening/day.

From that photograph that you have posted, every audio level is set to zero, so you won`t hear anything at all. Move the sliders to the right to increase volume, etc

Hopefully you figured this out, but just in case anyone else searches for this.

From the main screen you will have four options:

• Start
• WBPlay
• Change Profile
• Options

Choose the bottom box for Options (which will display in whichever language is selected.

Then, go right twice to the audio/sound options (looks like a speaker). The options are:

• Listening Environment
• Master Volume (slider)
• Sound effects volume (slider)
• Dialog volume (slider)
• Music volume (slider)
• Play speaker test
• Subtitles
• Audio Language
• Text Language

Change the bottom two to the language of your choice (from supported languages)/
