A:Answer The soundbar is a terminal device, which means that it need to be receiving input from all the other devices that produce the audio, such as your satellite receiver and DVD player.
You need to either connect the TV to the soundbar via the digital optical cable, or have the output of the HDMI port selector connected to the input of the soundbar and then the output from the soundbar to the input of the TV.
Alternatively, if both your TV and soundbar, depending on models, support Samsung Sound Share, you can connect them wirelessly.
