My TV has crappy speakers (they all do these days)
I have a cheap T-class amplifier plugged into it, powering some decent speakers. I leave it turned on because the idle power draw is very low and it’s annoying to walk across the room every time I turn the TV on or off.
But still. There’s a very slight hiss, and it’s the principle of the thing.
How can I turn the amp on when the TV is on, and turn it off when the TV is off, without drawing much/any power when it’s off?
The amp has 12V power supply rated at 2A
