Question SPDIF_O to Optical In. PC to Home Theater

[RavenXxXx]

I brought this from my Local online shop(Shopee Asia), a 3-pin SPDIF Daughter Card(+5v, spdif, gnd) to be specific. then my Motherboard is GA-A320M-DS2(v 1.0), my Home theater is a Samsung DVD Home Theater System C330(HT-C330)Asia.
I follow the instruction I found on the seller, my motherboard's manual and on the internet. Then I saw a red light so I thought its working but its not and I check the Optical cable and its working good. Installing some drivers(from gigabyte-fail, realtek-fail, modded drivers-fail) At the moment my drivers got corrupted so ill reformat this later.

Please Help. Thank you.

What exactly did you buy with the optical output? For the drivers, you need drivers for whatever sound card you bought not "some drivers".
