Question
I have a cable box, Sony DVD Home Theatre System DAV-HDX576WF, Samsung Blu-ray Player
all running to my LG TV through 3 HDMI cables. I have an optical cable running from my cable
box to my Home theater system. I am getting sound through my Home theatre system when
we watch TV or DVD'S however we are only getting video from the Blu-ray and only TV audio.

I only have one optical port on the Home Theater System do I need to get a splitter and run
another optical cable directly from the Blue-Ray to the Home Theater System? Also should
the optical be running from your Cable Box to the Home Theater System or from your Home
theater system to your TV?

Answer
According to the specs online for your home theater system, you should have another digital input (a coaxial one - typically an orange RCA connection). If your Blu-Ray player or cable box has a coaxial digital output, you could use that connection as well as the optical. They both carry the same signal, one is just electrical and one is light.

There isn't such thing as an optical splitter - and if there was, it wouldn't work very well. You can find switches, but those can be quite expensive.

I hope this helps you out!
