    Hi folks , I'm having the devil of a job trying to get the sound running on a friend's PC . XP Pro (32-bit) installed on Asrock Conroe Presler 775i945GZ (64-bit) motherboard . I've installed chipset and realtek audio drivers appropriate to the mobo (from Asrock site) but Device Manager still shows an unknown PCI Device under Other Devices and onboard sound isn't working . There are no PCI cards installed and onboard audio is enabled in BIOS . Could there be an issue with a 32-bit OS being installed on a 64-bit mobo ? I wouldn't have thought so but have little experience with 64-bit .

    Any thoughts on this would be greatly appreciated :)

    Try right clicking the device and click update drivers
    and let it search for the driver to see if it can find it.
    May want to let it search on the web too.

    Thanks leroys1000 . I've tried that but wasn't surprised I had no joy . That rarely works when Windows doesnt know what kind of device it is . I'm thinking it's a bus controller but other than that I'm totally at a loss !

    It could be the sound as onboard sound is still a PCI device.
    Is the audio device listed in device manager?

    No audio device listed but having loaded the audio driver without success I assumed it must be something else but related . I'm at the edge of my knowledge here so bear with me :)

    In the absence of an installed audio device would adding a PCI sound card be futile ?

    Sholdn't be a problem.
    Make sure to disable the onboard in the BIOS
    to avoid conficts.

    Marking this as solved though I never managed to get the mobo sound card working . Added an extenal USB SoundBlaster as a workaround and everyone's happy .

    Thanks very much for your help , leroys1000 :)
