After you install Windows Vista Service Pack 1 (SP1), you may experience one or more of the following problems with sound:

• No sound is produced when you play audio files or run programs that have an audio component.

• The speaker symbol next to the clock in the notification area may display the following message:

No Audio Output Device is installed

• The Sound Controller in Device Manager displays a yellow exclamation point

Solution 1

Verify that the default output device is set correctly

After you install Windows Vista SP1, you may find that the default output device, also known as the playback device, has changed.

To set the default device, follow these steps

  • Click Start, type Sound in the Start Search box, and then click Sound in the search results at the top of the Start menu.
  • Click the Playback tab. A check mark is displayed next to the default device. For most users, the default device is Speakers.
  • Click the item that you want to set as the default device, and then click Set Default.
  • Click OK to save your settings and to close the Sound dialog box.

Solution 2

Reload the current sound driver

To do this, follow these steps

  • Click Start, type Device Manager in the Start Search box, and then press ENTER.
  • In the Device Manager dialog box, expand Sound, video, and game controllers.
  • Locate the audio device that was included with the computer.
  • Right-click the device, and then click Properties.
  • Click the Driver tab.
  • Click Uninstall.
  • Make sure that the Delete the Driver Software for this device check box is cleared, and then click OK.
  • In the Device Manager dialog box, click the Action menu, and then click Scan for hardware changes.

You should see a message that a hardware device is being installed. Additionally, the uninstalled audio device is now present in Device Manager.

  • Close the Device Manager dialog box, and then determine whether you can hear sound.

  1. I tried both of the methods and niether of them worked for me. I have my volume settings at highest and it’s for sure unmuted. Yet no audio is comming through the speakers.

    This happened without warning for me one day. Not after I installed SP1. The sound just died after about a week of doing a system restore.

    I’m running an Alienware m9750 latop with integrated Realtek HD audio. The machine has worked wonders for me since I got it christmas 07. But this sound issue only happened a couple days ago and I’m yet to find a solution. Disabling, re-enabling, uninstalling, reinstalling, enabling different options, updating drivers, you name it I’ve tried it. And nothing works for me so far.

    The oddest part is that I get no error messages and windows seems to think everything is working just fine. Yet I hear nothing.

    If anyone can help, please email me a solution.

  2. Yeah. No help with either of those.

  22. Didn’t work for me.

    I’ve never had sound on Vista, ever since I installed it (installed with SP1 included). In Control Panel -> Sound I have only a ‘Digital Output Device’ and very few options.

    Teddy – maybe SP3 or SP4. I’d retreat deeper into the mother*board and wait for winter – worked for my people in WWII : )

  23. Hi ya, I tried the 2nd solution. It worked well for me. Thanks for the post.


  24. Thanks so much, Fix#2 worked for me and was super easy and quick, glad I found this before I started unnecessarily stressing!

  29. Thanks a bunch! Solution 2 brought my sound back. Very helpful!

  30. Thanks! Solution 2 worked for me on a brand new Lenovo G530 with Windows Vista Basic. Saw other sites suggesting K-Lite SoundPac or something and another suggestion CC Cleaner but neither were necessary. Much Appreciated!

  31. Thanks for the advice. Solution 2 fixed the problem.

  32. Hello,

    i have experiencing this kind of problem neither of your solution fix my problem. I found my solution here i thought id share this solution

  33. I also had no sound on my old xp computer after installing Vista, and had no luck with the above. I went to the Sony site ( i have a Sony computer)and entered my model number, Sony had drivers for my sound card. I downloaded and installed the drivers, at first the computer said the drivers were for xp and nothing changed, then vista said it could try to make them work, it did it’s thing, rebooted and now i have sound again. Hope this helps someone.

  34. A HUGE thank you for your help!! This worked great after not having any sound for over a week.

  35. thank you finally step by step instructions with no
    parts left out or skipped over works fine now
    THANKS AGAIN!!!!!!!!!!!!!!!

  36. After trying every possible fix/uninstall/scan and still no sound after Vista SP1 installation I randomly tried Control Panel > Hardware and Sound > Device Manager > Action(on top toolbar) > Scan for hardware changes and the sound just started working??!! As I said completely random but somehow it worked, hope this helps someone!

  37. Sorry, I should have also mentioned under Device Manager, I had expanded Sound, video and game controllers and had Conexant High Definition SmartAudio HD2 (installed on my Toshiba laptop) highlighted, then selected > Action > Scan for hardware changes, when the sound came back.

  38. Will follow information on this document; however, I do not wish to continue correspondence.
