In case anyone doesn't know, 24Hz output is working again with the latest (September) firmware for FireTV 4K. You have to set resolution to "Auto" for it to work in the FireTV preferences and of course the appropriate screen refresh setting in KODI. To get it smooth, though, I had to switch Acceleration from Media Codec to Media Surface acceleration. Otherwise, it "hiccups" every so often. I can confirm this worked on the DTS capable "shitty" version of 17.4. Volume control (on non-passthrough) also still works in 17.3 and 17.4 (I had to change the remote control functions to get the FTV remote to change it; I set it to up/down in full screen).
