I have a similar situation - I have my Cable box, ATV, Shield and Xbox - I use two devices: Rocketswitch HDMI switch along with HDFury AVRKey to get Atmos through K950 and HDR on my TV - best of both worlds.
OK, thanks. That's the way I have it now. One question, though.
If I get a device that supports Dolby Atmos, will this still work? Or, will I need to connect that device directly to the soundbar?
