Our Roku 4 is pretty much HDMI only output. So it plugs into one of multiple HDMI ports on our AV receiver or, into the second HDMI port directly on the TV.
I see no mention of composite outputs or Bluetooth on any of the Roku models.
Looking at the brief Concertone description I don't see any mention of HDMI switching or in or out. Only mention of a 3.5mm audio input for mp3 players etc. and Bluetooth. (Perhaps the headphone jack on the Roku, some remotes, could be patched into this receiver option? [awkward]).
If this did work, I'd expect syncing issues (lips & speech) as those Roku remote's use WiFi to communicate.
There is some mention (Concertone) of an optional panel that I'd suspect is a composite (RCA) type patch for a game console or the like, which would not be of much help.
Perhaps someone else out there has a hack?
