Oh dear, two confliciting answers (almost). Now i'm confused! The TV is a new Samsung UE46D5520 LED HD 1080p TV, 46 Inch with Built-in Freeview and the Cinema system is nothing high-end but also new, Samsung HT-D4500 Blu-ray/DVD Home Cinema System.. Any thoughts, anyone?If you want pseudo surround sound from the TV (tuner, network features) then you will need some form of audio connection between the TV and the home cinema system. If the TV and home cinema are new and have Audio Return Channel (ARC) then you should be able to achieve this with the HDMI cable only. If one or both don't then you will need to connect up the optical cable between the TV and home cinema.
Thanks for that, I tried a couple of DVD's, one was 'Sin City', which sounded great, sound coming out of all speakers, then i tried 'This Is England 86' which was originally on Channel 4 and the sound came out only from the front centre speaker and the front left and right but not the two rear speakers, so I bought the optical cable thinking that might change things but it didn't make a blind bit of difference, the TV programme sound still comes out of the TV speaker.. And 'This Is England' was the same as before.
