sound/AUDIO problem on HP COMPAQ DC7100

Hey guys,

I've installed Windows 7 and it really looks neat and fast, but I have one problem and it's getting my soundcard working.

I've downloaded the vista drivers from HP from HP Compaq dc7100 Small Form Factor PC*-* Download drivers and software - HP Business Support Center

Ive run it in compatibility mode on operating system Windows Vista and installed them. Now theres an exclamation mark in Device manager.

Ive uninstalled the drivers so it would be clean:
During the install windows7 asks me this:
When the installer says: Installation complete I look in the device manager and see this:

The strange thing is the files dmkaud.sys and dm.sys
cant be found anywhere on my system.

How can I fix this guys? What can I do?
