Hello,
I have a LG HT356SD home theater, It supports Dolby Digital surround sound , but it has no digital ports what so ever , the only way to produce Digital surround right now is from a DVD/CD or ?USB flash drive?. I want to connect the 3x 3.5 aux connections for PC somewhere on the LG HT356SD-s board, I want to know if that is in any way possible?

AMPs : 2x http://www.ti.com.cn/cn/lit/ds/symlink/tas5342la.pdf
Stereo Audio ADC : https://www.cirrus.com/en/pubs/proDatasheet/CS5346_PP3.pdf

I tried connecting one aux cable to the CS5346 (right to PIN 12, left to PIN 11, ground to PIN 13) and feeding a signal from the pc through the aux cable but no luck , i also tried it in every single mode ( Tuner, Aux, Portable, CD/DVD etc.)

You mean... you tried to feed the signal directly into the 20-pin connector?
Fun... anyway, if you don't have a digital input, or numerous inputs for each channel, the only other option would be to figure out how to use the 20-port connector, or rely on something like the 'Dolby Pro Logic II' system for faux-Surround sound. They encode surround audio on the L/R channel. It's not perfect but may be the only option you have without buying new hardware or digging into that 20-pin connector.

No, I connected to the CS5346, I just mentioned the 20 pin port that connects the Reader and the board because i thought i might hitch a ride on one of his leads if he carries analog audio.
