I'm sure I installed it correctly, and i'm using a headphone to listen to my soundcard and I using a smaller headphone jack to bigger headphone jack which I used to try to listen to it but doesn't work.

EDIT: It's working i'm using the RCA left and right cable via Headphone to listen through it. But i'm not sure if it's working because I not sure if i'm hearing any difference to be quite honest compare to the motherboard.

I'll try to mess around with my computer since this is the first time using a soundcard and if I can' get it to work i'll just post pictures and someone can point out what I should do.
