No sound on Vista after installing SP1/SP2 with Realtek


I encountered a strange problem on the computer of my parents-in-law office. After an installation of SP1 (and later SP2) no sound stereo speakers that is connected to the computer to an outlet.

The computer is an Acer Aspire T180 with a built-in audio device Realtek HD (5.1, but the connected speakers are two standard PC speakers), and the operating system is Vista. Before installing SP1, the sound was working properly, and absolutely no software or hardware changes have been completed.

My troubleshooting so far include:

-Tested with a helmet and another pair of speakers that I know works

-I have obviously checked that nothing is cut in all available parameters, or speakers

-Tried each input/output on the back of the computer, as well as on the front

-Checked in "output devices" that the speakers are connected and checked by default device

-Tried the two codecs/drivers available here:

-Tried the drivers of avaiable supplied directly from Realtek:

-Uninstalled Realtek everything (both in the Device Manager and programs) and let Vista automatically install the original drivers

-Disabled the 'digital output device (s/PDIF)"which is in the list of devices in output/game

-Unchecked the 'detect connection on the front"in Realtek audio manager program

-In addition, SP2 has been installed, which did not help. In addition, I tried every setting available, uninstalled/installed and so on. During music playback (or test tones Realtek or Windows sounds) all is apparently looking for OK with indicators of volume, jumping up and down, but everything is quiet.

So I'm out of ideas and cannot understand this. I am very grateful for any help and advice. Thank you!

After doing your restore point.

Go to Device Manager - click anywhere in the blank area - then click on VIEW - show hidden devices

Look around your Sound Device - If found click right on - UNINSTALL and when the box appears
-REMOVE the pilot - REBOOT - reinstall your latest driver - do not forget to check the version of the Device Manager
that they could rollback and you will need to install the driver - reboot - check until the correct version shows

  • Vista - after installing SP1 computer does not.

    Have a laptop with Vista.  After several months of trying to download & install SP1 and failing repeatedly (connection problems - too many wireless phones, etc. in the area) I finally took the computer to my home, got ' weak ' neighbor, successfully downloaded the MS, began installing and I'm not clear if it was completely installed or not.  I guess that this is a not restart (not stopped?) when installing as I was warned.  I came back to a blank black screen and it will not shut off/down and it will not also power upward.  Help!

  • After a reset of vista, it was impossible to install SP1 SP2 so

    as stated above - sorry, 1st time here

    After a reset of vista, it was impossible to install SP1 SP2 so. Finally, it was done via remote control by m/s. If I restore to new testament, I have the same problem? (looks and deliver it with the "build" number)

    I don't know because I don't know what was the problem in the installation of SP1 and SP2.  It is possible that the same issue may occur again.  I don't know any specific build of Vista which has particular problems associated with MS, but I'm not a expert on the Windows updates - if Microsoft Support tells you that it is possible that this is the case.  It may very well work the next time, or you may encounter the same problems again - who knows.  In any case, it is really not that you can do about it, unless you want to buy another copy of Vista with a different "build number" so that you can improve the chances that the upgrades will work without any problem (but do you really want to spend the money on that when all it takes) (, it's a lttle help to get install them again the situation would occur again?).

    I hope this helps.  If you have any other questions regarding updates Windows, including Service Packs, please post in the Windows Update Forum at: where the updates, including service packs experts will be more than happy to help you with your questions or problems.

    If restore work not and you do not have a Vista DVD from Microsoft, do a repair disc to do a Startup Repair:

    Download the ISO on the link provided and make a record of repair time it starts.

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

    When you have changed that, insert the Bootable disk you did in the drive and reboot.

    Link above shows what the process looks like and a manual, it load the repair options.

It cannot be used to install or reinstall Windows Vista, and is just a Windows PE interface to recovering your PC.

  • Could not start the desktop Vista after installing Windows Vista SP2, error: 0XC0190036.

    Original title: vista sp2 problem.

    I have a laptop that I haven't used in a while.  I took on a trip and received the message that the updates are available.  One was SP2.  After the update is complete, it failed to start with a message OXC0190036.

    Startup Repair said that he could not solve the problem.  Restoration of the system has not only restore - labeled SP1 and it allows you to finalize the restoration of files and stays there.  (I waited for 3 hours without change).
    I have a XP install disc that I used before installing Win 7 on my desktop, but it does not give me the opportunity to do an installation.
    Can enter the command prompt, I'm perplexed as to what to do.
    I want to get this laptop that works so I can give to someone who needs a faster machine.

    XP disk will not help you to fix Vista

    As the system restore does not try a startup repair and / or a restoration of the system using a Microsoft Vista DVD

    Manufacturers recovery disks normally do not have Service Options; they are normally a relocation to the factory only settings option.

    Here is the guide to repair Options using a Vista DVD from Microsoft.

    If a friend or a work acquantance of yours has one, you can borrow and use it for repairs.

    Table of contents

    1. Overview of Windows Vista repair options
    2. How to perform an automatic repair of Windows Vista using Startup Repair
    3. Advanced Tools Overview
    4. Conclusion

    If you do not or can not borrow a Microsoft DVD there is a download of a file ISO of Vista Startup Repair available that you can put on a Bootable floppy to make the above startup repair and that the method is recommended by a large number of posters in these Forums.

    Unfortunately, you have to buy it.

    Here is a link to it:


    And here are a few ways to reinstall Vista.

    There is no Windows Vista downloads available from Microsoft.

    You can contact your computer manufacturer and ask them to send you a set of recovery disks.

    They should do this for a small fee.

    And if you have never received a recovery disk when you bought your computer, there should be a recovery Partition on the hard drive to reinstall Vista on how you purchased your computer.

    The recovery process can be started by pressing a particular combination of the key or keys at startup. (Power on / start)

    Maybe it's F10, F11, Alt + F10, etc., depending on the manufacturer.

    Ask them to the proper key sequence.

    You can also borrow and use a Microsoft Vista DVD, which contains the files for the different editions of Vista (Home Basic, Home Premium, Business and Ultimate) must be installed. The product key on your computer / Laptop box determines what Edition is installed.

    Other manufacturers recovery DVDs are should not be used for this purpose.

    And you need to know the version of 'bit' for Vista, as 32-bit and 64-bit editions come on different DVDs

    Here's how to do a clean install of Vista using a DVD of Vista from Microsoft:

    "How to do a clean install and configure with a full Version of Vista '

    And once the operating system is installed, go to your computer manufacturer's website and get the latest drivers for your particular model or laptop computer.

    And phone Activation may be necessary when you use the above installation method.

  • Windows XP sp3 can not access the network shares on vista after installing sp2

    I have a xp sp3 computer and another currently running vista Home premium sp2. Previously, I was able to access the network share on the xp computer before vista computer I installed sp1. Both computers were able to ping between them without problem.

    I've upgraded to sp2 because I had problems with windows media center, missing records. Upgrade of these issues fixed, but this means that roll back to sp1 is not an option for me to get operational network.

    Please do not post a standard answer on the network configuration. I am familiar with the standards requirements to share files between xp and vista and everything is set up correctly.  Like I said everything was working fine before the installation of sp2.

    If it is a known problem that is still not resolved, I'd appreciate knowing that information as well.

    Edit: Firewall been disabled during my troubleshooting

    After more work, I was able to solve my problem.  Update zone alarm solved my problem and helped my windows xp machine to access my Vista network shares.  As I pointed out in the original post, zone alarm firewall has been disabled during my troubleshooting.  Apparently, when disabled, the old version of zone alarm has always been the origin of the problem.

  • Computer fails to boot after installing SP1

    I use Vista without SP1 for quite awhile. I've just updated to SP1 since the message kept popping on my screen. Now the computer will not book. I used the original vista bootable CD and clicked on repair. He began the process of repair, but got stuck at the same registry error

    !!! 0xc01a001d! 35032/165955 (\Registry\Machine\COMPONENTS\DerivedDat...)

    Thus, even the repair doesn't seem to work

    I need to fix this since I have a lot of important files on my hard drive.

    Support for Vista Gold (no Service Pack) ended on Tuesday, April 13, 2010. If you get only to try to install SP1 (and it is NOT yet installed), ALSO lack you the value of six months of critical security updates. Therefore, it is almost 99.9% certainty that you see the effects of a long infection date hijackware.


    Cleaning a compromised system

    Personal data backup (which none should be considered 100% reliable at this point) then format the HARD disk and do a clean install of Windows. Please note that a repair installation (upgrade AKA on-site) will NOT fix it!

    NOTE: If your computer came with a set of disks, there is a hidden partition restore (not to be confused with the restoration of the system) you would use to do the clean install (AKA a "destructive recovery").

    After the new installation, you will have the equivalent of a "new computer" in order to take care of EVERYTHING on the next page before connecting the machine to the internet or one local network (i.e. other computers) AND BEFORE to plug in a flash, SD card, or any other external drive to the computer otherwise:

    VERY IMPORTANT! -Online any Norton or McAfee free trial which is preinstalled on the computer when you bought will be reinstalled (but invalid) when Windows is reinstalled. You MUST uninstall the trial for free AND download/run the removal tool appropriate prior to installing the updates, Windows Service Packs or IE upgrades AND BEFORE installing your new anti-virus application.

    Run the disk error checking.

    Run the System Update tool.
    So if these tools did not report any errors, then install the SP1.

    Thank you


    After installing another OS, you can retrieve only Vista if you start from the Toshiba Recovery disk and install the content. There is no disk HARD recovery option more, it means that the HARD drive recovery partition will not help you.
    In addition the Windows RE partition has nothing to do with Toshiba, it s a Vista feature.

    Then boot from the Toshiba recovery disc and will respond to factory settings! ;)
