rgb/dvi audio in not working?

[user9346]

I got a 3.5mm mini-RCA stereo audio cable to plug in my s-master digital amplifier as an external speaker. my TV has the AUDIO IN (RGB/DVI) plug in. For some reason connecting it does not produce any sound whatsoever. I have tried plugging the jack on my phone, and the audio works fine. The settings on the DVD are all correct. and I'm thinking it has something to do with the TV.

The model of the TV is LG 50PA6500

if anyone knows anything, that would really help.

For transmitting audio signal from tv to amplifier you'd have to use the audio out port, which I see is optical only. Check if similar port available on the amplifier.
