SoundMAX Integrated Digital Audio stopped working

Hello,
I have a problem with SoundMAX Integrated Digital Audio on my HP - nc6220 laptop, WinXP professional sp2.

SoundMAX Integrated Digital Audio just stopped working, I tried reinstalling it but it always says that there was a problem during installation and it might not work properly.

In Control Panel>Sounds and Audio devices it's all grayed out so I cannot do anything there.
In device manager there is a yellow exclamation mark, I tried disable-enable but it does not help.
I also tried updating the driver, re-enabling windows audio in services, even reinstalled Windows and installing sp3.

Also I tried an USB sound card and it is working well.

Is there anything else I could do, or maybe SoundMAX Integrated Digital Audio is just broken and cannot be fixed?
