Windows 7 Ultimate x64

Hi guys,

My name is Frederico and Im from Brazil...
I have try to resolve this issue on the last week but without success. (sorry my bad English lol)

Windows 7 x64 Ultimate - M4A785-M - VIA VT1708S HD

I fallow this steps:

1 - Update last BIOS firmaware
2 - Disable on-board Video HD audio (HDMI) TI4200
3 - Enable on-board HD audio controler and front panel type HD audio
4 - Update Windows
5 - Install the chipset drivers from ASUS site
6 - In Device Manager delete all audio device and reboot
7 - Try to install the last driver from ASUS site and get the fallow error:

"We can't found HD audio device" and Fail to Installed components :
VIA HD Audio Codec Driver v7. :0xfffffffe

I try use realteck drivers follow all the steps above and nothing happens. When I try show "Playback devices" its show only "High definition audio device" "not plugged in" and nothing happen if I plug speakers in front or back...

I don't have any idea what i have to try now...

Please you guys find any more else about this issue?
