Hi,,
If you are using HDMi cable from Home theater to samsung lcd tv then no need of Optical cable..since the High Defenition Digital audio is getting from HDMi interface..

Hello, I just bought a Samsung Httz512 Home Theatre System to go with my Samsung LN46A630 HDTV. I have wired everything including the Monster HMDI cables from the reciever to the TV.
Are the Optical cables necessary to complete my hookup? I understand they are to go from my Dish Digital Box to my Home theatre reciever. Will this complete my wiring setup? The instuctions are a little confusing to me this being my first Home Theatre setup....
Is the optical cable necessary to make the Home Theatre work properly?
Thanks in advance
