A:AnswerCheck your connections. You should be going out of the TV to the sound bar. Then you have to go into TV menu and select sound settings with the sounder on. In there it show up as a line item to select from. Doing this mine connected right up.
A:AnswerAm not sure as I hooked directly to tv.. I do not see any places to connect. However, the digital output can could plug into a receiver and the receiver then broadcast to your speakers if you have a sound system.
A:AnswerI bought the soundbar for the same reason. Going the same route has worked out well for me so far. That is surround sound first and then adjusting bass and treble tones as needed. It’s worked out very well for me so far
