i looked up your tv, it says "Optical digital audio output for Dolby® Digital"
I suspect that is only available from the built in ATSC tuner. And, of course, the program material has to have a DD 5.1 soundtrack. Any other source, it would be stereo only, or through-put.
If you have a cable or sat STB, connect it directly to the HTIB with optical cable.
