UPDATE: You do not need to enable “Developer Options” as I show in this video, if you don’t want to. It was just a habit of mine from hacking on phones, but later realized it’s not necessary. It doesn’t hurt anything, but if you’d like, you can skip it and just enable Unknown Sources directly.
A small walk through on how to side load apps, particularly Kodi, on your new Sony TV.
***EDIT*** — The TV DOES support audio pass through of DD/DTS over optical out (tested and confirmed) and DD/DTS HD codecs via HDMI ARC (untested, but theoretically this should not be a problem — if somebody tests it, please let me know). You must enable audio pass through in your Kodi settings, just like any other Kodi device.
