Hi, i have a wlt68 Toshiba TV, ***** i know!! but will have to do for now, just bought a Samsung HT-D5100 Blu-Ray 5.1 Surround Sound System, and also have Sky HD. I have so far my Sky HD with HDMI to TV, Samsung Blu-Ray to TV with HDMI and Optical out from Sky to Blu-Ray. I put the required setting on the Blu-Ray for Optical but get no sound. The cable is beaming red no problem. If i watch a DVD surround works, If i take the Optical out of Sky and put into back of TV i can get freeview surround but whatever i do i get no Sky surround and thats the main reason i bought it. Please help me i have no idea what to do next. Thanks.
