Realtek won't recognize my 5.1 speaker

Why, won't Realtek HIGH DEFINITION Audio allows one with 5.1 speakers to select 5.1 speakers?
I tried rebooting.. Windows a pain always needing to restart.
Tried reinstalling drivers
Tried downloading alternative medicine (other softwares)

But its still an unresolved issue, taking lots of coffee while writing this, well the next best thing is to select stereo speakers for Realtek HD Audio, at least sound comes out from all speakers, but I have no control over the volume, quality, rendering etc.

End notes
1. the 5.1 speakers connects to a hub that transfers the sound via a 3.5mm jack and not a HDMI as the sound system does not have one!

Any solution to this malady?
