In my case I have a new LG TV and a Yamaha soundbar which I hook up to my Nvidia Shield . Both have the option to pass through signals to the other, BUT when the soundbar is in the middle the HDR signal is lost and when the TV is in the middle the Atmos signal is lost. Across reddit I’m also reading posts from people with similar problems.
How hard can it be to literally transfer the entire signal from an input to an output port? I am truly confounded.

The problem with it is *licensing* and *compliance*.
HDMI is a closed standard with copy protection functionality built in.
Equipment that is allowed to actually listen in on everything that is transmitted and just pick out the bits it wants and resubmit the entire stream again, is very, very expensive. Because it’s restricted in the licensing price model to the point where it doesn’t end up in consumer electronics.
Added to that, HDMI passthrough doesn’t necessarily mean that the signal is just passed through. It means that the signal is resent again with the passthrough equipments capability taken into account; the reason that the soundbar tosses HDR to the winds is that it’s not HDR compliant. It cannot resend with a signal capability that it’s incapable of resending with.
This is one of the more annoying things with HDMI; you pretty much have to buy the exact same tech generation of all of your electronics, to keep up with the development.
