This seems like the right thread to ask: Has anyone seen a HDMI-CEC embeddable amplifier board?
I'd love to DIY some speakers or a soundbar, maybe something like the Tech Ingredients "Worlds Best Speakers". But the convenience snob in me doesn't want to go back to a Harmony, or other multi-system remote. I've gotten really spoiled by being able to use my TV remote to control the soundbar volume, TV, chromecast, etc... all over HDMI.
I've done some searches for an amplifier board, like the youtubers are using to make homemade soundbars. Either I don't know the right combination of search terms, or they just don't seem to make such a thing. I don't REALLY want to make a bunch of space for a receiver, I'm fairly space constrained in the TV area because reasons.
