RCA home audio problem?

I have a ps3 and a bluray player hooked up to my tv via HDMI. The tv is a samsung c7000 55in 3d led 240hz tv. I have an optical audio cable from the tv to the surround sound system which is a RCA RT2906E 5.1 system. But yet i have no sound. Someone please assist me.

You have to select the source input on the surround system to get the sound to come out. It will not automatically switch to the device you want to hear from. Your owners manual will provide that instruction for you. Hope this will help you out.
