Mean that there is no assurance it (a)works and (b)anyone including the maker can make it work.

On top of that, when you call one maker they can point a finger at the other maker and you end up getting nowhere.

This is why I connect with Optical for such setups. But then again, settings can be annoying to find. On top of that, not only do you have to set the TV to output on Optical but some APPS have you fishing inside the app to select optical.

-> You are not wrong in thinking "what a mess."
