Windows 7 - No Audio Output Device is installed

Hi guys, i just installed Windows 7 put all drivers, but audio don't want to install, said that smth about "no device found to install driver".
Sound Icon is with a red circle with a "x". In Device manager no sound device as all. I have a Hp Dv 9925nr with audio conexant 221.

Please Help (sorry for my english) !!!

Hey.

Right click on the audio device in the device manager. Properties. Details tab. Change dropdown to hardware ids. Copy and paste the results here.

I'll try to find or edit a driver that will work for you.

In device manager i don't have the sound icon, i don't where is it ?!!

Go into the bios and see that the onboard audio is enabled.

If so, please post a screenshot of the device manager with the sound section maximized.

Here is what I found under "hardware ids".

HDAUDIO\FUNC_01&VEN_10EC&DEV_0880&SUBSYS_1462E603&REV_1008
HDAUDIO\FUNC_01&VEN_10EC&DEV_0880&SUBSYS_1462E603

The soundcard is onboard on a "MSI RS482M4" and Windows finds a driver durring install, but yet I get the message "No Audio Output Device is installed" :-(

I allready installed the ATI chopset drivers from MSI's homepage,
but the sound drivers has no effect.

Hope you can help me.
