I just hooked up a home theater system and have a problem with the sound from the TV and the speakers. Maybe "home theater" is too grand a description, so I'll tell you what it is and then what the problem is. I have a new Sansung blu-ray, a new Samsung 3D TV, a 3D high def cable box, and a traditional but high-end stereo system. The stereo system includes two big Snell III speakers, a Balanced Audio Technology (BAT) integrated tube type preamp and amplifier, a Apple TV for wireless transmission of music from my computer, and a DAC from ps audio to connect the Apple to the BAT. The Blu-ray is connected to the TV by HDMI cable, and to the BAT by audio (analog) cable. The cable box is connected the same way - to the TV by HDMI, to the BAT by audio (analog) cable. All of these connections are among those recommended by the respective manuals. When I hooked up the Samsung stuff, I found that I could not get the audio from the TV (when playing from the Blu-ray or from the cable box) to sync with the audio through the stereo system. The timing is slightly off, as if there were a echo, or the whole thing was taking place in a hugh stone cathedral. There is a menu on the TV that will take my to a screen from which I can adjust a delay in the audio from the TV, but doing so does not cure the problem. I know that I can play the audio either through the TV and not through the stereo, or through the stereo and not through the TV, but I would like to be able to use both. I called Samsung's "customer service" people twice and was told by two different Samsung people that the signal travels faster through the HDMI cable than through the audio cable. My understanding is that the electrons involved travel close to the speed of light in each case, and that Samsung's explanation is either (1) a totally cynical attempt to hoodwink a customer into believing that he can not do what the Samsung manual says he can do, or (2) an honest communication of an astounding ignorance. I'm hoping that someone on this site will know more about this than Samsung and may be able to help.
