If the home cine doesn't have an optical then you can use red & White phono to red and White phono. On your tv the out will have a circle with a small arrow pointing outwards on it and the cine system will have a circle with an arrow pointing inwards. Otherwise u can use 3.5mm jack to red n White cable and go from the tv headphone jack to the afire mentioned on ur cine system. The source on ur h/c should be set to aux I'd reckon aswell. If that's no use then goodluck .
