Hi, my name is ***** ***** I will do my best to help you today. To make sure I don’t miss anything, please give me a minute to review your question.
Is there any other video source/ device connected to TV beside the Sky Box?
OK, does the DVD player has Digital Audio Out (optical out) port?
Let me get the info that will help to suggest best connection setup.
No problem, take your time.
Nice, please connect Sky box HDMI Out into HDMI In of sound system, connect HDMI Out of sound system in HDMI-1 Input of TV, select HDMI-1 input in TV and select HDMI In of sound system with its remote to get Sky box picture on TV and sound through sound system.
For DVD, please connect optical cable between Digital Out of DVD and Digital In of sound system, you would need to select Digital Input with sound system remote when need to watch DVD disc to get sound through sound system where as need to change video input in TV as usual to get DVD player picture on TV.
There is another way that is bit simple. Plug Optical Cable in Digital Out port at back of TV and hook it in Digital Input of sound system, select Digital input in sound system with its remote to get sound whatever is being played/ watched on TV. I hope these info will help. If you have any additional questions, feel free to ask. If you're satisfied, please rate me a 5-star at the top of your page. Thank you.
OK, no problem. Take your time.
