I am trying to connect a Samsung UN65ES 8000FXZA TV, a Blu Ray DVD Player BD-E6500, and my Spectrum cable box to an LG Wi-Fi Sound Bar Model SKC9. The TV/Cable lash up works fine as I have both picture and sound. I have connected something wrong when introducing the Blu Ray DVD Player as I get picture but no sound when trying to play a DVD. I suspect my error is in connecting the DVD player to the sound bar. I am hopeful you can walk me thru setting up my system with HDMI and fiber optical cables. Thanks
