Realtek HD audio manager interface not showing advanced settings

Thank's for looking.
I have a Asus-G74sx-91234z laptop,last week when i plugged in headphone i started to hear sound coming from both headphone and the laptop speakers,a quick google search told me change some settings in Realtek HD audio manager,when i opened the user interface i found my realtek HD audio manager interface is totally different from others not having advanced setting options at all!!
I tried power of THX true studio, also installed the latest driver too,i even asked this question in asus rog forum ,nobody replied yet

G74SX- Realtek audio manager user interface NOT SHOWING ADVANCED SETTINGS!!!!

This is how my GUI looks like..


instead of the normal one like this..

Any advice much appreciated,thank's.

Thank you Fireberd, even though i tried installing the driver from Realtek before after reading your post i thought i give another go,this time i uninstalled the previous drivers ,restart the computer then installed the latest driver,after installing i got some surprise,i couldn't find Realtek interface at all!!! Audio is working but couldn't find the interface!!!

Pls check the image

Thank's,its there-I opened the interface,still it looks same,don't know how to short out this issue,when i plugin headphones sound coming from both laptop speakers and headphones!!

It was fine before,happened recently,as far as my knowledge i didn't install new software!!!
