Question

No sound out of home cinema when watching tv both samsung connected with hdmi cable?

Answer 1

Peter is bang on.  Your RCA audio cables also need to be connected.

Answer 2

I have a samsung lcd and home cinema as well- U have to plug Your home cinema(at next to the HDMI cable - audio out) with TV's  audio in(left right) with a RCA cable(black-red).Then You should hear and see on aux. The hdmi is not enough it  just works at me if I'm watching dvd. Hope I helped.

Answer 3

If you want sound through the TV's speakers, make sure audio over HDMI is PCM (or LPCM) and NOT Dolby Digital or bitstream. Most TVs don't accept DD over HDMI but they will accept PCM.
