    After installing this optional Windows VISTA update, I get the error that "No
    Audio Output Device is Installed". What happened and how do I fix it?

    Same thing happened to my on my Gateway laptop. I went back to the SigmaTel
    audio drivers and all is good again. Frankly, I don't know why I was
    upgrading if the first place because my audio was fine.

    original gateway driver and it works again.

    this happened to me

    i just when to the dell website (my laptop is a dell) and downloaded the
    'new' drivers and installed them, after that everything was ok..

    i dont know why windows update would install something that would do that...

  6. The IDT audio update is due to an issue with Vista SP1. Many installs
    have an older version of one of the driver files that is not compatible.
    Unforunately, the one offered by Microsoft is screwing up many

    If you have a recent Dell desktop, you can try R173209.exe from Dell:

    The web page says it's for an Optilex 740, but internally it says this:

    In addition, it works find on my XPS410, which is similar to the
    Dimension 9200.

    After updating my audio, I was able to download and install SP1 through
    Windows Update. My only scare is that after the SP1 update, Windows
    defaulted to a USB headset instead of my speakers. I had to go into the
    Sound settings and change the default back.

  7. I am having this same problem with my gateway after downloading the
    Vista update. I cant see to fix the problem. I have uninstalled the
    vista update. My computer installed the software for Sigma Tel High
    Definition Audio CODEC and said it was "ready to use" but i am still
    getting the No Audio Output Device installed, and my sound isnt
    working.... does anyone know how to fix it? I would really really
    appreciate the help.

  8. You can't just roll back the driver - you need to go back previous restore

    Yes, that's what I did too. I misstated above.

    Same thing happened to me. I just went back to the old driver and everything
    was fine. Not sure why it did what it did

  11. This optional update was also offered to me last week. Knowing my
    audio is not "IDT", I simply right-clicked on it and put a check-mark
    beside "Hide".

    In fact, I feel confident that if I were to unhide this update, it
    would again be offered to me.

    My question to those in the Cloud is:

    "Why is Microsoft offering this optional update to so many who do not
    need it, or want it?"

    I also ask any official Microsoft representative to respond, if he
    reads this post.

    Of course, I flatter myself to even consider that Microsoft would
    reply in a Usenet newsgroup to such a person as myself.

  12. In 2006, IDT took over the audio codec chip production from SigmaTel,
    which is usually identified as STAC.
    Andrew Rossmann, May 8, 2008
  13. That may be so, but my Dell (bought last month) refers to the Audio
    chip as "STAC98xx". Additionally, there are no entries for "IDT"
    anywhere in my Registry. Nor are there any such entries on the Dell
    driver installation disk. Nor is such a codec driver offered on
    Dell's Driver Support site for my particular machine.

    IN fact, I've never seen such drivers offered by Microsoft Update on
    ANY Dell I've owned, until it was offered after I installed Service
    Pack 1.

    How this got offered on Windows Update for my particular audio codec,
    I will never know. All I do know is that this update is causing many
    others lots of problems.

    This is not the first time Windows Update has offered me a "poisonous"
    unneeded update before. For years, Windows would offer me an HP CD
    driver (of course, I had no such HP CD/DVD drives). The ONLY time I
    installed the bugger, I wound up having to reinstall the OS.

    I assure you, I began looking carefully at such driver updates on
    Windows Update, and have not repeated my mistake since then. I prefer
    getting my drivers from my PC manufacturer, anyway. Never had good
    luck with the drivers offered on Microsoft Update.

  14. Windows Update was looking for a file named STWRT.SYS. It then looks at
    the version of that file. If it was or older, it offered the
    update. Unfortunately, it appears it may also have updated other files
    that caused compatibility problems. Since this is usually built into a
    motherboard, there could be minor differences on some.
    Andrew Rossmann, May 9, 2008
  15. Strange: Version Tracker Pro shows no such update for my machine. In
    fact, all it shows for Audio is the "SigmaTel High Definition Audio
    Codec." Nor does it show any updates available.

    My opinion?
    STAY AWAY from any such "IDT" updates unless you are SURE they are for
    your machine.

    And, "If it works already fairly-well, there is no need to update". As
    they say, "No need to fix what's not broken."
