Ok, make sure your speaker settings are exact to this image. Scroll down a bit and you will see the image and the legend to tell whats what. Make sure your speakers are connected the way it shows in the picture. Then once everything is hooked up, let me know if the problem is still there.

*Note* If you don't have an HD setup, this can prove problematic.
Also, your audio system has 3 plugs coming off of it to plug into your computer:
Black is for your Rear Speakers
Orange is for your Center/Subwoofer
Green is for your Front
If your computer only has Green/Pink/Blue you may not be able to use this system to its full potential because of the lack of ports.
Green - Audio
Pink - Microphone
Blue - Line-in (Extra Audio that may not work for Rear Speaker Setup)
In order for this sound system to work flawlessly with your computer you need to plug in the cords like so:
Black -> Black
Orange -> Orange
Green -> Green
This below will not work properly:
Green -> Green
Orange -> Pink
Black -> Blue
If I'm not mistaken, that's what you said you are currently connected like. That pink is a Microphone jack. And the blue is the audio.
If your Realtek can emulate and change the jacks, this can work, but you will be without a microphone unless you hook in through USB.
For your Realtek settings, I need you to change the following (or see if you can):
Change Blue from Line-In(Default) to Rear Speakers
Change Pink from Microphone(Default) to Center/Subwoofer
Leave green as Stereo.
IF you can change these, it might just work. If you can't, and you do NOT have dedicated Black and Orange ports, you may have to get a sound card that does, or you can only use the stereo system as a 2.1 instead of a 5.1.
Let me know what you find.
