Yeah, I thought you already tried that. VLC has no way to change default audio that works. I've tried. I use GOM player when I use rear speakers.

Sorry for the fail.

Go to Control Panel-->Sounds and Audio-->Audio. Click on Advanced. Set to "Desktop Stereo."

VLC checks Windows Audio every time it starts and sets itself to that setting.

I have no idea why your 2x2 system plays no sound in the front.
