Hi Keith, that is really interesting. My Sharp bar connects to the Sony TV via ARC output. My Humax, is not connected directly to the soundbar, just to another HDMI socket on TV. Are you saying I should connect the soundbar directly to the Humax with this device? Is that a similar set up to your Yamaha?
Colirv: Unfortunately, there is no optical audio IN on the Sharp Bar. Which is annoying as I have this cable.
