In game voice chat is not working at all with Xbox xCloud and Game pass.

Hi there B5K5 welcome to the community forum! Christopher here, an Xbox fan just like you and has been on Xbox for years already. I would really love to make your day by helping you out. If you got 2 separate speaker drivers in sound settings disable the one that uses your pc speakers

Go to windows search bar and type sound settings will take you there

Click on sound control panel from there unplug your headset first so you know which one is the pc speaker and disable that before you plug your headset back in

This problem is not only coming with Xcloud app but rather all the other things related to it eg. If I want to see the list of all games in xbox game pass ultimate. This works fine with Xboxes own app.

Well no changing the store wouldn't work

One your account region must match your physical region as xcloud is based on your physical region

Better question are in you a supported xcloud region

Not all games pass ultimate regions are xcloud

Q

Xcloud isn't available on PC yet.

The only way to play via a PC/Laptop is via an Android emulator such as Bluestacks.

How to Play Xbox Games on PC With BlueStacks and xCloud

This should work fine on your laptop specs. Remember, Xcloud is a streaming service, all the graphics processing is done server side and sent to your device. That's why it can run on Android phones.

Streaming should work fine on your laptop but it's not powerful enough to run PC Game Pass titles natively. Your machine is probably one of Dell's flagship 'Inspiron' range from about 3 years ago. Fine for basic productivity, awful for gaming.

Hello again, you are using the xCloud service in this case may have come out because the service catalog is not the same as the Game Pass, xCloud does not have all the games.
