Hi, my name is Marvina and I will be happy to help you.

I'm sorry you have this problem. Follow the instructions below for a solution.

If you're having trouble installing or running a game from the Xbox app on your PC or Windows device, try the following solutions.

Solutions
As simple as this. A simple reboot can fix many things.
Press the Home button on the taskbar, type settings, and select Settings.
In Windows 10, select Update & security. In Windows 11, select Windows Update.

On the Windows Update tab, select Check for updates to see if updates are available for your device.
After downloading the updates, select Install now to start the installation.

After installation, we recommend that you restart your device so that the latest updates are applied.
For more information, go to:

Windows Update
Press the Home button on the taskbar, type store, and open the Microsoft Store app.
Select Library.

Under Updates and downloads, check to see if there are any updates available for the Xbox app or Gaming Services. If an update is available, select Update.

Hello, first it's a pleasure to be able to help you today.

My name is welcome to the community.

Hello Atrayne06, when it says that the sound keeps going of your console out, would that be on your television, or on some sound system that the Xbox is connected to?

Does this happen with all games and in the console menu, or just with some specific game?

What model would your Xbox be?

Have you tried any procedures in the console, whether it's rem regarding the system as a cache cleanup or resetting the console?

If you can give more details, I'll be waiting for your reply.

Although it does work, some games don't have window borderless they have window fullscreen would that be fine, it does work I've only tested it for one game, but is there any other way to find out what's causing this tabbing out like a third party app?
