Been searching the internet and can't seem to find a solution to this so I figured it's time to post. I just recently got a GWC USB 5.1 Channel Audo Adapter AA1500 5.1 Channels USB Interface Sound Card
I'm using an older Logitech X-530 5.1 surround system and have plugged in the green, orange, and black cords correctly in their respective positions yet I do not get sound from the center or rear speakers. The subwoofer, left, and right speakers are working fine.
Any help and suggestions would be greatly appreciated. Thank you.
Edit: and then I found the CD sandwiched in the folds of cardboard *facepalm*
