Windows 7: Problems? With Realtek

Sooooooooo... Hey guys Whatcha doin'? Me nothin'. So I have problems. Maybe it's not problems, maybe I am just stupid... maybe. Soooo. I downloaded Realtek drivers for Windows Vista & 7, version 6.0.1.6101. So. The thing is, that only ''speakers'' works as a device, maybe it should be, maybe not, but Digital Output is not working. No sound. When I select it as main device, no sound. Maybe it should be like this, I don't know, just tell meh. Ohhh and not to create another thread, my Fn keys (the blue ones) are not working. Just drivin' me crazy. I have i think it is ASUS Z96S laptop or should it call ASUS Tek Z96S. Maybe everything will sound crazyyy but help meh. Sorry if there was a thread about it. Just couldn't find it. Thanks for those who are gonna help ;> <3

see if you can update all your drivers through here.

Even the Chipset, BIOS, Audio

Yes, but will you help me with the Digital Output? Is it needed? At all, WHAT IS IT?

EDIT: Should I download drivers for Win Vista 32bit when i'm using windows 7 32bit?

As I saw, sound flashes when i'm listening to music, but i can't hear it. so any ideas what is going on? I reinstalled drivers, didn't helped.
