I've hooked up a few components to my amazon fire stick tv's "equipment manager", which is their system for using their remote to control all of your gear (via IR). My Harman Kardon AVR works perfectly with it, for example. I turn the volume up and down on the first stick remote and keep the HK remote in the drawer.
Fire stick seems to work with basically every device that can accept a universal IR remote but it doesn't seem to be working with The Fives. Anyone have experience with this?
