Hi All
I go an answer from Samsung, have pasted it below
Dear Richard Evans
Thank you for contacting Samsung Electronics.
The usual connection method we recommend is to connect the home cinema
system or amplifier to the TV itself.
The home cinema system/amplifier will take the sound from anything
showing on the TV e.g. PS3
This helps reducing the connections you need if you have more than one
unit connected to the TV.

I hope this has been of some assistance to you. If you do have any
further queries, please do not hesitate to contact us.
Kind Regards
Franziska
