Apple voice once worked perfectly, but hasn't worked for weeks.
Channel up/down buttons don't work with Dish Hopper.
Pretty tired of continuous trouble shooting. Removed and re-added to the project, rebooted each piece of the puzzle individually and all at once (wifi, Halo, Core1, ATV, Dish Hopper, TV) talked nicely to it, re-added it to ATV, cycled Siri control on/off/on.
