Cec and arc have been broken every update

the xbox has CEC/ARC pre-historic !

ARC is Audio Return Channel. It allows a TV's audio to be sent back to the attached receiver via the HDMI Out of the receiver instead of having to run a separate audio line from the TV to the receiver. It's intended for use when using a TV's internal tuner
via an attached antenna or cable source.



HDMI CEC is what allows your TV's remote to control other components without actually programming the remote with the code for the other devices.



HDMI CEC pre-dates ARC by several revisions. Unfortunately, few things take advantage of it.

Blows my mind that the Xbox one S doesn't support CEC when PS3 did. Makes no sense.

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.

Hello again, yes you're right, for some reason there's some conflict in the system and it hasn't been fixed yet, it seems.
