Sigma Tel High Definition Audio Codec Problem

I just finished upgrading to Vista. Everything seemed to go OK, everything installed correctly except for the Sigma Tel High Definition drivers. I have no sound and an X'ed out sound icon in the task bar. I checked all the obvious things, cables and volume but no change.  I uninstalled & reinstalled the sound device & drivers through the Control Panel & now I have nothing!  The Device Manager now says the card i working properly, but when I click on the volume icon it tells me that the audio service is not running.  Any suggestions?

    Roll the driver back to the XP version, this is a known problem for Vista upgrades.

    I had the same problem (XPS410) here's what I did to fix: Went to control panel then devices and uninstalled the sigmatel driver and also checked the box to remove the software. Then I downloaded the new driver from the Dell support site for Vista. Problem fixed.

    Thanks for the quick feedback. I have an XPS/Dimension 410/9200.
     
    I've uninstalled & re-installed using the drivers listed on the Dell support list for my configuration. Specifically SIGMATEL STAC 92XX C-Major HD Audio, dated 07/25/2006, v.5.10.0.4991, A07.
     
    Is there a way to determine which are the XP vs Vista drivers?
     
    Thanks again for your patience.

    OK, I went to the driver download site for my confiuration, switched the operating system to Vista from XP, downloaded the most recent driver, uninstalled the XP version (including deleting the driver software) & re-installed. It now finds the device & says it's working properly, but I still get the red X through the icon and the associated message "the audio service is not running". How do I get the audio service running?
     
    I appreciate all of your help & patience . . .

    Thanks for your help. Not to sound like a , but where might I find the Dell Vista Support site? How about a URL?

    I don't have my m1210 in front of me now,
    so I'm only recalling from memory;
     
    My Computer, right click, manage
     
    There should be a link to Scheduled Tasks
     
    Under multimedia,
    there would be a trigger/action on starting the service.
    there's also a key under HKLM/Software/Microsoft/Windows/CurrentVersion/Run
    for something called Xaudio.exe or something.
     
    There are several related services for multimedia;
    I haven't tried to tweak all of them so I can't tell for sure what you can disable
    and what you can't.

    well, you can show My Computer on the desktop,
    by going to the Windows icon (Start),
    when it expands, there's My Computer on the right column,
    right click on it,
    Check - Show on Desktop
     
    You could of course also, access the Manage option there.
     
    Now that I have my m1210 -
     
    Under Computer Management,
    System Tools,
       Expand ->Task Scheduler
     
    Task Scheduler Library, Microsoft, Windows
     
    **At this point I have already deleted most of the triggers
    so there's only Bluetooth,
    CerrtificateServicesClient,
    MobilePC, and
    SyncCenter **
     
    but I'm digressing.
    I re-read your post and you said that you did an upgrade.
     
    When I do an installation (i've never done an upgrade);
    I always download all the drivers first; that's probably what you need to do.
    go to Dell's website, enter your service tag, choose the appropriate Operating System (OS),
    then it will list the type of drivers available.
     
    download that Sigmatel and install it.
    that will probably solve your problem.
    Since you're there, you might as well download all the other drivers;
    for those that are not working but you may not be aware of,
    you can check the status under device manager.
     
    Good Luck!
