Samsung AU9000 + Powered Subwoofer + External Speakers


Hope fully this is the right place to ask.
I have a Samsung AU9000 + Optical to RCA converter(USB powered) + Powered Subwoofer + External Speakers.
I would like to know if someone has gotten this to work.
My amplifier is not working properly so I removed it from my setup.

EDIT: Removed some outdated info, removed my silly idea, added new info.

Does anyone know if and how I can get the external speakers to play sound rather than the TV Speakers?
Current setup: TV Optical port-> Optical to RCA converter-> Powered Subwoofer-> External speakers.

NEW info: I went out and bought a usb powered optical to rca converter.
From optical on TV to converter, from converter to L+R RCA ports on Subwoofer, from Speaker outputs on Subwoofer to External Speakers.

I swapped the settings in Sound menu on the TV, between TV Speakers and Optical.

On Optical I got bass but nothing from the external speakers or TV Speakers.

On TV Speakers, the Subwoofer is working but no sound from the External Speakers, only from the TV Speakers.

I havent tried swapping between manual and automatic power on the subwoofer(its a small switch) before playing music. Ill try that and report back tommorrow.

The Subwoofer is a KEF PSW 2000 - 1x Red RCA + 1x White RCA Line Input ports and 1x Red + 1x White High pass outputs. No optical port on the sub
1x Pair Speaker Output screw-down terminals output and 1x Pair Speaker Input which has the same terminal as the Output terminals.

Please see the picture.
Any help or advice would be greatly appreciated.

You have no sound because those RCA Phono sockets on your TV are inputs not outputs.
Modern TV's haven't had RCA Phono analogue audio outputs for a few years now.

You won't get speakers working connected to the sub without a separate amp.
The sub needs high level (speaker outputs) from an amp.
