I have a problem with our new Compaq 8510p laptops, since we need to run Win XP on them for some months yet.
I have installed all the drivers from the HP support XP Pro site, but I still have one unknown device. It claims the device is on the HD Audio bus, but I already have the soundcard and modem there. (Which is the two devices there on the preinstalled Vista installation)
The device id is:
Anyone have any idea to what it might be and where I can find the driver for it?
I have attached a zip file with images of the installed components. (Unfortunately their names are in Danish)

this is called cpu throttling - when full CPU power isn't required, it's going slower and it can save a lot of energy. This needs support in CPU chip.

After that you should be able to install the real sound card driver, which can be found at the HP site as well.

I looked in the Control Panel -> Sound+Audio Devices
the issue is with ATI. When you install the ATI drivers after installing sound (which is default for the reinstall disks provided by HP), the ATI takes over the drivers for the default sound. To fix the issue, I simply changed the default sound back to the SoundMAX HD Device and all is normal.
SIDENOTE: The reason that you have the ATI driver taking over the sound from the Soundmax is to enable full functionality on the HDMI Port. If you intend to use the HDMI for both video and sound, i would presume that you would have to set the sound output default back to the ATI driver in the same location...
