Honestly most of why I'm thinking about soundbars is that I am annoyed by all the crap I'm having to do to trick my game consoles into outputting 5.1 bitstream sound to a TV reporting 2.1 support and I want something that acts like a modern HDMI 2.2 receiver. But I don't know of anything designed to be a cheap re-encoder to DTS (5.1)-over-optical from an HDMI 2.2 input (which would need to pass the video signal through)
