Xbox App on Windows 10 loses streaming sound when TV connected to Xbox One turns off

Hello AbsolutPauer!

This type of issue would depend also on the TV that is being used and the way it is configured. Please take a look at the steps here:

Troubleshooting Xbox app game streaming on Windows 10

It sounds like when the TV is being turned off it sends a signal to the console letting it know that there is no display available so you lose connection on your PC. Xbox One consoles normally do not boot all the way up unless they are connected to a compatible
display. You may want to contact the manufacturer of the TV to see if there is any setting available to disable its communication with connected devices.

Please let me know if this helps and thank you for reaching out!

Here's some additional details for Microsoft. I am using two xbox ones and a windows 10 pc:

- an original model xbox one connected to a 1080p tv and a wireless AC network connection

- an xbox one S connected to a 4K tv and wired networking

- windows 10 pc with a 1080p monitor and wired networking

Game streaming works perfectly to the original model xbox one with a wireless connection. From my windows 10 PC I can turn on the console, start streaming, and the resolution is great.

With the xbox one S though, even though I have a wired network connection to both the PC and that xbox, I will only be able to stream in 640x480 resolution unless I turn on the TV before I try to stream. I can also report that if I do turn on the TV first
and begin streaming in 1080p, I can then turn off the TV without affecting my 1080p streaming until I turn the xbox off.

This appears to be a bug for our particular configuration, and it's not getting any attention from Microsoft because their streaming test cases are passing. It could be a difference of original model xbox vs. xbox one S, but I'm expecting it has something
to do with the 4K display settings on the xbox, HDCP, and/or trying to stream to a lower resolution of 1080p.

The Xbox One streams wirelessly to a pc that has windows 10 and the Xbox app installed on it.

It does not matter that a TV is connected to the Xbox One. The console does need to be powered on to stream.

This can be done between Windows 10 and an Xbox One console with more recent updates.

Note that this is currently, as of my post, in Beta. It also will require a decent network connection between the PC and the console (preferably an Ethernet connection though I've done it before over WiFi as
well). You will need an Xbox controller connected to the PC to control the console (I've used an Xbox 360 wired controller and it works just fine).

What you need is an Xbox One and a Windows 10 computer connected to the same network. Install the Xbox app from the Windows 10 app store. When it is installed, run it and log in. Look in the app for an icon
that looks like an Xbox One. Tap or click it and it will let you connect to an Xbox One on the network.

The console will initially have to be on so that it can find it on the network and register it with the app. You may also have to enable streaming in the Xbox One settings to allow this feature to work. After
it is registered with the PC, you can turn the console on by initiating a connection from the app.

Only some apps are allowed to stream to the PC. Notably, from my experience, you cannot watch TV or certain video content while streaming to the PC.

hope this helps
