You can do on/off using an IR blaster (broadlink integration with discrete on/off codes). It’s when you want to read volume etc things get trickier
I have an automation that turns on amplifier only when using certain inputs, not just when the TV is turned on. I can easily imagine people would also configure their amps to use different input depending on TV input.
