    I just bought a notebook Lenovo G450 and I had drivers not found
    problem. My OS is Windows XP SP2. In Device Manager, there are four
    "Audio Device on High Definition Audio Bus" device with exclamation
    mark. Below is the screenshot of my device manager.

    There is no sound problem since I had successfully installed the sound
    driver from lenovo (The name is "Conexant High Definition SmartAudio
    221" as you can see on the screenshot above) and the sound is working
    without problem. I also had installed Microsoft UAA Bus Driver before
    installing the sound driver.

    I had tried installing realtek and nvidia high definition audio driver
    and all required drivers from lenovo
    ( http://consumersupport.lenovo.com/en/DriversDownloads/drivers_list.aspx?CategoryID=370748),
    but still no avail. The four yellow exclamation marks is still exist.

    So I need help to identify what actually are the devices that shown as
    "Audio Device on High Definition Audio Bus"? And where can I get the
    driver for that devices?

    These are the device IDs:
    HDAUDIO\FUNC_01&VEN_10DE&DEV_000B&SUBSYS_10DE0101&REV_1001\5&15CAAF27&0&0001
    HDAUDIO\FUNC_01&VEN_10DE&DEV_000B&SUBSYS_10DE0101&REV_1001\5&15CAAF27&0&0101
    HDAUDIO\FUNC_01&VEN_10DE&DEV_000B&SUBSYS_10DE0101&REV_1001\5&15CAAF27&0&0201
    HDAUDIO\FUNC_01&VEN_10DE&DEV_000B&SUBSYS_10DE0101&REV_1001\5&15CAAF27&0&0301

    I already searched the device ID with google, but cannot found any
    information about them.



    Thank you in advance.

    I just solved the problem :p
    The four devices are NVIDIA High Definition Audio that the driver is included in NVIDIA Display Driver installer from lenovo.

    I should install Microsoft UAA High Definition Audio driver first before installing the NVIDIA Display Driver. What I did before was I installed the NVIDIA Display Driver first before installing UAA High Definition Audio driver, that's why the four NVIDIA High Definition Audio driver weren't detected, hence the drivers weren't installed.

    So the solution is just simply reinstall the NVIDIA Display Driver.

    Just to follow up, if you install SP3, it has the UAA driver. Thanks for posting back.
