    Hi Newbie Here:

    OK, I have had the same problem that I have read about in here and many
    other places too. Some have answers, but they are not to my operating system
    nor brand of Laptop. I bought a Dell XPS M2010 last month and after windows
    made the update:

    "IDT - Audio - IDT High Definition Audio CODEC"

    on my laptop, and now I have NO sound (but I guess I'm not alone). I tried
    rolling back the driver in the device manager, no luck. I tried booting my
    laptop to the last known good configuration, no luck. I've tried inserting
    a couple of CDs that came with my PC, but once they were open, I didn't
    understand what was what so I didn't mess with a thing. Has Any body come up
    with a solution fro an XPS Dell that is easy for a novice to fix?

    PS I HAVE learned from reading these posts to NEVER update drivers from
    Windows updates, thanks for teaching me that (it's a hard lesson to learn).

    Thanks in advanced!

    Thanks for the fast reply. I have checked for updates, but I am not sure if
    I am doing it "manually". If I go to Microsoft's web site, it tells me to go
    back and: "Click the Start button, click All Programs, and then click Windows
    Update." Which is the only way I know how. I have been checking everyday
    for something to fix it. You see I have Windows Vista Ultimate, and that it
    the only way I know to check for updates. I guess I should have mentioned my
    operating system and a few other specs about my laptop just in case it would
    help. Here are some specs of my system:

    Model:...............................Dell XPS 2010
    Operating System:............Microsoft Windows Vista Ultimate SP1
    Processor:.........................Intel Core 2 Duo T7600 (2.33GHz / 667MHz
    / 4MA)
    Memory:...........................4GB Dual Channel DDR2 SDRAM at 667MHz (2
    Hard Drive:.......................RAID Protection 250BG (2x250GB) 7200RPM
    Internal Optical Drive:......Slot Load Blu-ray Disc Drive (BD/DVD/CD burner
    with BD write capability)
    Video Card:......................256MB ATI MOBILITY RADEON X1800
    Wireless Cards:................Intel Next-Gen Wireless-N
    Sound Options:................Integrated Sound Blaster Audigy HD Software
    LCD Panel:......................20.1 inch WSXGA+ Wide Screen with TrueLife
    and Integrated Web Cam

    If you can think of anything else, please let me know. Oh yeah, I also have
    all of the Disks that came with my system, but I have no clue which one might
    have the info I need or how to use it. I tried putting a couple in and
    couldn't make sense of it.

    Thanks again!

  4. Sounds like you're doing it manually. You can't use Windows Update website
    in Vista.

    Hey Thanks for all of your help! Really, all of those links you gave me will
    help me for more than just this. I finally called Dell, I wasn't sure if
    they would help since it was a Microsoft problem, but they did! For anyone
    else that needs this download here is the link to it. My sound works just
    great after that! Thanks for all of your help!! Have a Terrific Day!

    Yes it is, but when i lost the sound it hadn't uploaded yet. I lost the sound
    two weeks ago and got SP1 last week.

  8. I'm sure the fact that MS recently started offering the correct driver
    update to machines that haven't been offered SP1 yet doesn't give you any
    comfort. Still, I'm glad to hear you got the problem sorted with Dell's

    well, PA Bear, Windows Update has not offered the "right" IDT/Sigmatel High
    Definition Audio drivers for Dell machines, so Vista users who use
    IDT/Sigmatel audio on Dell computers must obtain updated audio drivers from
    the Dell support site instead of Windows Update.

    My mother's Dell Inspiron e1405 notebook computer originally came with
    Sigmatel 92xx audio drivers for Vista from the R147073.EXE
    package. Since those drivers were not up to Vista SP1 standards, I
    downloaded and used the R171788.exe package from the Dell support site a few
    months ago to update the Sigmatel high def. audio drivers to v6.10.0.5614.
    even though R171788 didn't list the model number of the Dell laptop, the
    package did work because the updated drivers found a qualifying "hardware id"
    number and still have sound & was able to update to Vista SP1 with no loss of

    You can gather the hardware identification number information of a Sigmatel
    high definition audio device by opening the Device Manager window by typing
    DEVMGMT.MSC in Vista's Run dialog box, expand the "Sound, video and game
    controllers" section to reveal "Sigmatel High Definition Audio Codec",
    double-click on that to view its Properties, click on the Details tab, then
    change the Property that says "Device Description" to "Hardware IDs".
