I have an Insignia TV model #NS-50L240A13 which has a Coaxial digital Output connection. I also have a Samsung 5.1CH Blu-Ray Home Entertainment System which is used as my audio receiver for my Insignia TV. The Samsung unit has an input jack for optical digital audio. I have tried using the Impact Coaxial to Optical Converter model #40018, however it could only process SPDIF PCM signals only and would not decode the SPDIF RAW signals thereby limiting audio output to two audio channels only. I am looking for advice on where I can obtain a working Coaxial digital to Optical digital converter that can process the RAW audio signals so that my Samsung receiver is able to decode the Dolby Pro Logic 5.1 audio signals.
