I tried the search bar but didn't see anything related and I watched the YouTube video. The video says to select "DM" on the amplifier (if that's what it is) but my Connex system doesn't have a DM selection. For movie surround sound I have to select "Optical" and the speakers work great. But none of the selections, including HDMI will activate any additional speakers to enhance the TV's two speakers. Maybe someone can help.
Thanks.
