Vista - Newest Realtek HD Audio Manager no longer includes SPEAKER FILL option

Question:

Where is the Speaker Fill option (play music on all 5 speakers) in the latest version of this driver's HD Audio Manager?

Background:

Recently I updated my drivers from the Realtek website. I have a 5.1 speaker system but the problem is ever since I updated to the latest version, Realtek HD Audio Manager no longer has the "Speaker Fill" option... so basically only 2 of my 5 speakers will play audio!

I don't understand why they would remove this option in the latest version. I could simply refer to an older version but the new version has something I really want which is Secondary Audio Output for Headphones (helps me DJ).

I tried replying to this topic about the same issue but it was too old: working out how to get 5.1 in Vista

Also, that topic did not answer my question because the "Speaker Fill" option is absent from my Vista Speaker control options

you could still use the secondary output for headphones with the old realtek drivers and control panel, just double click on the output from the headphone socket within the realtek panel and click on front speaker out, this will change it to 2 outputs for the same audio, I would upload a pic to demonstrate but I'm not on my pc at the moment, I'm on my G/Fs notebook.
