    I have now used the whole weekend trying to get sound on my MCE
    machine...with no luck so far...

    I get the message that there is "No Audio Output Device" innstalled,
    although I have installed the realtek driver etc.

    BUT - you write "analog" sound. I am using Logitech 5.1 speaker system, and
    thought that this was digital sound.

    It also seems that my biggest problem with the sound card, is that the Modem
    on the same card does noe get recognized, and makes a lot of trouble in the
    device manager etc.

    Any suggestions?

    I also had no audio on my laptop's (d900t) HD Audio card (Realtek ALC880)
    when I installed Vista Ultimate x86. Solved the problem by

    replacing the HD Audio Bus driver with an older version ( with
    I have deleted \Windows\Inf\hdaudbus.inf and

    \Windows\System32\Drivers\hdaudbus.sys. When Vista asked for the HD Audio
    Bus drivers I pointed to the right directory. I used the files

    from this package:


    If you downloaded the package from the above link you should extract its
    contents. Then you should extract the following file to:

    MSHDQFE\Win2K_XP\us\kb835221.exe. This contains the folder (commonfiles)
    where you must point to when Windows asks for the HDA Bus driver.


    I had to take ownership of the \Windows\System32\Drivers folder to delete


    After the driver downgrade I had installed Realtek HDA drivers for Vista
    v1.60. Now the audio is fine and Realtek HD Audio Manager is

    working too.


    Finally: Vista found an "unknown modem device" but I have no drivers
    installed to it. So it is not the modem that causes the problem.

    Correction... do not delete the inf file and do not use hardware wizard. Just
    copy the older hdaudbus.sys over the new one.
    I used WinRAR to extract the .exe's contents

    I installed Windows Vista 32bits ultimate on my clevo D900T,
    unfortunately I do not have a sound. If I am well your procedure it is
    enough to replace the driver hdaudbus.sys (version 6) by the driver for
    xindoxs XP (version 5). At the time I want to replace this file with the
    rights administrator a message appears: you must have an authorization
    to carry out this action. Do you have a solution to replace this file?
    Thank you by advance

    Sure! Go to C:\Windows\System32 and right click on Drivers folder. Select
    Properties and press the Advanced button. Switch to Owner tab and press
    Edit. After UAC confirmation a new dialog pops up. Select the user wich you
    want to have access to the directory in the "Change owner to" list and check
    in "Replace owner on subcontainers and objects". (I had selected the
    Administrators group.) Press OK. You have taken ownership of the folder.
    Now go back to the Permissions tab. Press Edit and add the desired user
    with full permissions. After you checked in "Replace all ex..." press OK.
    Restart your system in safe mode and owerwrite the hdaudbus.sys with the
    older version.
    I hope you will succeed.
