Hi all, My digital cable box has composite connections coming out that I connected to my a/v receiver. My question is, what type of sound is coming out of the cable box? I guess it depends on what is being broadcast by that particular station? But is it always stereo sound, is it sometimes mono, could it be 5.1 sound? I have heard that some digital cable boxes output dolby digital 5.1 sound? What type of connection do they use to do that, is it a digital cable connection or 5 analog audio connections? Any help is appreciated!
