Recently purchased Naka 9.2.4 surround system, trying to get it to work with Samsung UN60JU6500 TV (2015). Followed all install\/troubleshooting information, can't get it to work with TV using HDMI ARC ports. Demo works properly, Naka turns on & off with TV but there is no sound. When I do a CEC search the TV shows: (Nakamichi) as it's searching but then when the search is over it shows: "No device found". I have all TV settings as per instructions.
