RCA Output, Digital Input

Oct 8, 2018
Been looking around but not sure I am finding what I am looking for. Apologies for the noob question:

TV is RCA projection 52" (Model # P52950 - great service, no issues) with analog audio out. I have a satellite receiver, Blue Ray, and a VCR to the inputs 1 and 2 (no issues) and would love to play the TV audio through a LG home theater system (model # HB-905 TA). Of course, right now it is just the Blue Ray that is playing through the system.

I am thinking I need an analog to digital converter to go from the TV to the system. Am I on the right track? I tried a Neoteck DAC audio converter linked below but got no sound.


Any help would be greatly appreciated. TIA.
