I have the optical out on my direct tv satellite reciever going to my optical in on my home theatre and it works great.
I know you may not have that option but if you do, give it a try
I have a Samsung LE46B650T2 HD television and a Samsung HT-BD1252 5.1 channel Blu-ray Home cinema system. I have followed all the instructions for connecting leads etc and everything works i.e. TV is receiving sound and pictures and blu-ray is playing discs and surround sound speakers are all working. What I want to do is hear sound through the surround sound speakers when watching ordinary TV programmes and according to the instruction manual (pg 65) I should be able to through the Anynet+ function. However, when I go to the Anynet+ device list my home cinema system is not listed. I have made sure that Anynet+ (HDMI-CEC) is set to On in the Application menu. I have also connected the optical in jack of the home cinema system to the digital audio out (optical) jack of the tv, but I am still not getting sound out of the home cinema speakers when watching tv.
Can any one help please?
