5.1 Sound Realtek HD Audio (5.1 works in settings, but not outside)

Hi 7foums!

A lot of people seem to have this problem, however no [solved] posts seemed to fix the problem.

Specs & Set up:
OS: Windows 7 Ultimate x64
Motherboard: ASUS M5A99X EVO R2.0
Driver: Realtek HD R2.71 (Driver version: 6.0.1.6873)

In order to achieve 5.1 sound, I have the rear speakers connected to rear speaker out (black), center/sub to center/sub out (yellow) and then the front speakers to Front speaker out (green), and none connected to side speaker out.

To the problem:

The surround sound works perfectly when testing with 5.1 in the Realtek HD audio manager, and also in the Sound configuration. However 5.1 doesnt work anywhere else, VLC, system sounds etc, instead the sound comes from the front speakers only. I've tried every setting in VLC, but since the 5.1 doesnt work anywhere outside of configuration I assume that the problem lies somewhere else.

The settings are set to 5.1 and through speakers are placed as default, all chords are connected, and as I wrote, the sound works perfectly when testing in settings.

Does anyone have any idea what the problem is?

Tomorrow I'm going to try and rollback the drivers, but if anyone else has an idea for what I can do, please give tips. Might it be a windows 7 update issue?

For what its worth, I don't see "Speaker fill" option when I go into Settings > Sound > Speaker Properties > Enhancements, this has been listed as a solution for this problem, but I can't find it.

Sorry for the disjointed descriptions and I hope that my predicament is comprehensible, my only excuse is that I'm incredibly tired.

I have been using Shark for years. No problems. Just have to watch out when you install for the toolbar BS.
