Xbox Series-S sound mixer bar greyed out

Sorry it took so long to reply but in the mean time I did all the steps in the link provided and the headset chat mixer is still greyed out

As for the questions the problem started 3 days ago, the chat mixer was working before, no changes were made prior to the issue, and I am using the Xbox series x

Is the chat mixer option missing or greyed out?

This is done under Settings > Display & Sound > Sound Mixer. Adjust the mixer to give more or less volume to the main app vs. the side bar. Then use the volume as usual through the sound system.

Thanks for contacting us my name is Samy, I am advisor independent and I will be helping you today.

How are you, mate?
Can I know the steps you've already taken, mate? And could you go into audio settings and tell me how the settings are set?

Hi Dan!

What steps have you already tried?

Let's try to remove your profile and power cycle your console before adding your account back.

Note: Before doing these steps, please make sure that you know exactly the email address linked with your gamertag and the password to it so you can add the correct account again.

1. Remove account:
Press the Xbox button to open the guide. Select System > Settings > Account > Remove accounts. Select the account that you want to remove, and then select Remove to confirm. When you're finished, select Close.

2. Power cycle:
Press and hold the Xbox power button for 10 sec until it turns off. Unplug the power supply for 30 sec. Plug it back in and turn it on again.

3. Add account:
Press the Xbox button to open the guide. Select your gamerpic in the upper-left corner of the screen, move all the way down and select Add new.

Enter the email address for the Microsoft account that you want to add, and then select Enter.

If that doesn't work, best option is to perform a factory reset. There's an option to keep your games and apps.

Press the Xbox button to open the guide.
Select Profile & system > Settings > System > Console info.
Select Reset console.
On the Reset your console? Please choose “Reset and keep my games & apps”
