No surround sound

[The1der]

Hi All. 

I've got my cinema system connected directly from my Sky Q box by Optical Cable but I don't seem to be getting any sound from my surround speakers. 
everything is connected correctly (speaker test), I have audio from Front R/L/C & Sub.

Sky Q to Tv (Samsung Series 7) - HDMI 

Sky Q to Samsung Cimema System - Optical Cable.

has anyone got any ideas what settings I should have on all devices...???

How did you configure the sound settings in your TV if I might ask?

[The1der]

In the sound menu or system menu..???

[SjorsK]

Both, I wish to check everything to see if I can see a mistake

Tv Sound Menu:

Select Speaker - Reciever (HDMI)

Expert Settings,

HDMI Audio Format - PCM

Audio Format - Dolby Digital

Audio Delay - 40

Sound Feedback - Low

Ah, that explains it. Put it on PCM / Bitstream instead of PCM / Dolby Digital.

That should solve it. When you select Dolby Digital it converts the signal to what the TV itself support. But with bitstream it sends the signal as unmodified as possible to the reciever
