Maybe I'm way off base from what you're asking, but would a Raspberry Pi with an amplifier hat solve this?
I _think_ Rpi supports HDMI-CEC, but then again I've never seen CEC working properly outside of the fantasy realm

I've had pretty good luck with CEC with my 5 year old Samsung TV. Compared to my in-laws new house that has a Denon receiver and IR blasters and some universal remote, that they paid big bucks to have an AV company install, CEC is like a space age rocket ship!
