I just finished setting up living room with a 42" LG LN5300 and Samsung Crystal Air Track FM35. I connected the optical cable from the back of the TV to the Soundbar and I get no sound. This happens on both HDMI inputs. I have also tried connecting the cable directly from the cable box to the Soundbar and still nothing. I am losing my mind trying to get it to work. Has anyone else experienced this problem? Any ideas would be greatly appreciated. Thank you.
