Love this “hack”! Brilliant!That's not possible (at least at the moment). But as a workaround, if you don't need the mute button, you could teach the ATV the power button of your TV by pressing it when you set up volume control via IR. But because of the position of the mute button, I could imagine that you will turn off your TV accidentally several times, at least until you get used to it. But maybe it's a solution for some people.
