Hello,

I have had no sound on my laptop for over a year. And I finally found the answer to the problem and fixed it. It's so nice to have the sound back.

I have reposted the forum post here:

See http://www.crn.com/software/207500472.

This just happened to me (I listened to the automatic Windows Update and installed this optional update) - and I need to use my computer's audio to listen to watch and listen to [censored] DVDs for the [censored] project.

Vista people, if they haven't already got this update, really want to avoid getting it. It makes my computer unable to play audio anymore; even though device manager sees my audio hardware, Vista tells me down by the clock that "No Audio Output Device is installed".

And my computer's PC speaker beeps loudly every time a dialog box pops. It's driving me crazy (and, I suspect, those around me).

I found a Web site (http://www.microsoft.com/communities/newsgroups/list/en-us/default.aspx?...) where Microsoft recommended this RealTek driver (http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=23&...) to fix it. I tried it, but it didn't work.

However, I just got audio working again. Here's how:

1. Go to to "Control Panel > System" (WindowsKey+Pause|Break)
2. Click on "Device Manager"
3. Open the tree "Sound, video and game controllers"
4. Right-click on the audio device and choose "Properties"
5. Select the "Driver" tab
6. Click on the "Update Driver..." button
7. Choose the bottom button: "Browse my computer for driver software"
8. Choose the button _below_ the browse field: "Let me pick from a list of device drivers on my computer"
9. Choose the driver "High Definition Audio Device" (NOT "IDT High Definition Audio Codec")
10. Click "Next"
11. Click "Yes"
12. Wait for the original Vista driver to be reinstalled
13. Click "Close"

I hope no one else runs into this, but this fix worked for me. It doesn’t even need a reboot.

*** note that you may want to uninstall your old drivers beforehand - I don't know; a reboot may be necessary on some machines ***
