I have a Yamaha 106 soundbar that I'm trying to connect to the TV and DVD Player and PVR. The TV is a RCA 4K HDTV and I have a Sony dvd player. At the moment I have an optical cable going from the PVR to the soundbar and I have HDMI cables from the dvd, pvr and soundbar going to the Tv. I have sound on the TV but not the dvd player. I've tried connecting the optical cable from soundbar to TV as the manual suggests but dont' get sound that way. Any suggestions?
