HDMI-CEC Input switching need to be disabled for remote play

Yes the controller + adapter is up to date. The problem seems to be connected to how the console handles the hdmi output. It seems when the connection is not present anymore the console disables the output.

If somebody could test this on their console it could be really helpful. Basically change the input on the TV or Receiver the xbox is connected to and check if the headset still plays the xbox audio.

Maybe the issue is connected to my HDMI receiver and how it handles hdmi-switching. I also tried to disable HDMI-CEC and ARC but the problem still exists.

Olov,

I am not sure what the actual fix is here, however there are some things you can look at to see if it is the cause.

First make sure that your TV and sound bar are connected via whichever port is labeled as the ARC (Audio Return Channel) input. In addition to this, ensure the HDMI cable supports ARC.

Second check to see if Apple TV and the Xbox are fighting over control of the inputs. You can disable the HDMI-CEC function on the TV and see if the issue resolves itself. Generally, if I recall correctly, this is a per port setting with the TV on ports
that use the CEC function. Try turning CEC off on one or both HDMI ports on the TV and see if this fixes your issue. If your sound bar also has HDMI-CEC settings then that may be the culprit.

HDMI-CEC allows devices connected to your TV through HDMI ports to communicate back and forth with your TV. The devices can have some control
over the TV, and the TV can have some control over the devices. This means you could control your Blu-ray player through your TV remote, for example. Or devices can automatically change your TV’s input when they need to do something.

Also if have not done so, I generally advise firmware updates of both the TV and soundbar. Often these updates will include compatibility fixes.

The Xbox One doesn't use HDMI-CEC. Everything simply uses infrared commands. So it's not going to automatically switch inputs to the right one. I suppose it could switch an input if the TV is already on and the code to power on the TV changes the input
if the TV is already on.

I think that is an hdmi cec thing and should be a setting within your avr to sense the signal is in use and performs the auto switching of your input.

I think it'd be helpful to update this answer, since in theory it could've changed.

As of September 2019, no Xbox One model supports automatic routing of receiver/TV inputs to align to its HDMI-Out, or aligning power-on states, using HDMI-CEC.

Xbox One supports sending IR signals (through Kinect, IR extension cable, or via IR emitter on the console itself) to turn on/off receiver/TV, change volume, and control a cable box attached to its HDMI-In, but its IR system cannot be configured to route input
automatically. (The IR can be used to manually change inputs, e.g. using the Xbox mobile app emulating a traditional remote control.)

Comparisons are often made to Nintendo Switch, PS3/PS4, Apple TV, Chromecast, Roku, and Fire TV, all of which send commands over HDMI out that some TVs/receivers support for one-touch power-on and coordination of inputs. The standard those products use is
HDMI-CEC, which has a number of trade names, e.g. "Anynet+" or a variety of plays on "sync", "link", or "CEC."
