No audio from tv for apps netflix or USB source

[purpleturtle]

I have a new SONY TV - BRAVIA KDL-55W829B
I want to get audio from my 3 year old 5.1 surround sound system SSS. This surround sound works great from other source like the SKY + box.
I'm in the uk.
I haven't plugged in the old style aerial so I get the TV through the cable / dish twin feed and don't think that would be related but I mention this as the TV doesnt have any programs stored separate issue. Maybe the analogue aerial would fix that but isnt the cable digital - I kind of assume they are separate systems ??
Back to the lack of audio - I bought an optical audio cable as I thought the issue was that the USB plugs in the tv so the sound signal needs to get to the surround sound box and I thought the hdmi SHOULD be able to do that but I got desperate to try anything.
In the back of the surround system which is a samsung I have two input hdmi and a 3rd that is the one OUT for the tv (seems to enable two way control - so that the tv talk to the SSS).
the 2nd hdmi IN I use for xbox and the sound is fine - so if I had a third hdmi IN it feels like I need the tv to send back down to the SSS for it to then go back to the TV.

If I take out ALL the cables the situation is simple - the TV plays back without any box ! So thats why I thought I DO need the optical cable to run to the SSS. I have yet to try the headphones out into the SSS - not sure I have a cable for that. But the red and white LR cables should be as simple as it gets and that doesn't work. I'm using D-IN on the SSS.

I have the old RCA audio jacks to test that it might be the optical cable but again no sound.
I checked and played with the settings in the SSS and that changes nothing.

This has got me stumped ! Thanks for any ideas.

Let's make sure I understand your problem:
- you have TV Optical Out -> SSS Optical In, and SSS HDMI Out -> TV HDMI In
- whatever source is connected to your SSS plays OK (video / audio);
- aerial TV plugged into TV plays OK thru TV and thru SSS;
- SmartTV apps (Netflix) and USB sources play on TV only, but no sound comes into SSS;

Let's make sure I understand your problem:...

yes apart from the fact that I have no analogue aerial at all so I have not tested - aerial TV plugged into TV plays OK thru TV and thru SSS;..

but otherwise yes exactly as you say so if my xbox signal comes into SSS on hdmi2 then i select that in the TV then the sound is from SSS as expected. Anything fed through the SSS gets the sound from it ok. The TV doesnt have this same thing happening as the source IS the TV in this case.
I bet if I connected the USB through the SSS then that would work fine. BUT I can't believe that I must watch youtube and College Humour via the TV speakers if my optical audio is connected. It's almost like the optical isn't working but I have tried with red + white RCA cons too.

I would not be surprised if OpticalOut is just for Over-the-Air sound (albeit the manual does not say anything). I would rather ask Sony UK support directly - "Does OpticalOut / RCA L+R carries apps and USB audio?"
