So guys, I just bought a Samsung 40' 3DTV. At the back, there are 2 HDMI (1 is HDMI/DVI) ports, and a component/av in port. Now my 5.1 home theatre has 1 HDMI out and 1 Digital Optical In. I need help in making my PS3 play sounds in 5.1. Currently, My PS3 is connected to the HDMI/DVI of my TV. Then my home theatre is connected to the HDMI 2 of my TV. Still no sound. Why? Does it have to be like this; PS3 has a optical cable from PS3 to home theatre. (with HDMI connected to TV for picture.)?? Thanks!
