I tried that already. I can get blu Ray function but then I have no sound .... If I have sound I have no blu Ray function.
So you either have video from the bluray but no sound, or you do have sound but no video? Are you using an HDMI cable from the bluray to the soundbar, then another HDMI from the soundbar to the TV? If so, then there is something wrong with the soundbar. When connected properly, you should only hear the sound and see the video from the selected input only. You may need to exchange this soundbar for another.
