i have a Sony HT-CT150 3D Sound Bar hooked to my Sony 51" LCD tv through HDMI, the cable box has the optical cable going to the sound bar, then the subwoofer of the sound bar, distributes the sound and picture via HDMI.. it is hard to hear certain channels, some channels the commercials are loud and the show is quiet, others vice versa, its not like this on other tv's in my house with the same cable box, but no sound other than the tv speakers. if i dont use the sound bar's speakers and use the tv speakers, the volume is fine. i cant find any type of encoding or setting that will correct this.. does anyone have any insight?
