Trouble connecting JBL SB100 to Samsung 51" plasma. I have tried optical digital cabe from bar to TV and get no sound. I turned down TV speakers to zero. I tried selecting external speakers on TV menu. Still no sound.
The optical connection should work. Try changing the audio output type in the TV audio menu. Turn off the TV speakers in the Samsung audio menu rather than just turning the volume down. This might activate the optical out. Make sure to select the optical input on the soundbar.
