Smart-speaker based theater mode

It is a new feature that allows your TV to send back audio over eARC to your “media player” currently available for these 2 devices, please refer to the official docs:

Apple TV 4K

audio + videoATV4K 2genTVTVaudio over HDMI eARC

You need to have quite new Apple TV 4K (gen 2 released in May 2021) and at least one HomePod (or HomePod mini).

I have tested this setup with a quite new eARC enabled Samsung The Frame TV and my old ARC-less Epson projector (using method described here).

Amazon Fire TV Stick 4K Max

A very similar setup is possible with a similar set from Amazon. You need to have the “Max” version of the Fire TV stick and at least one Amazon Echo.

It is also required that you have an eARC enabled TV/projector as it will not work with the VAX04201 HDMI eARC Matrix!
