Help me enable audio on my Sony Laptop

[Atvar]

As the summary states, I recently removed vista on my Sony Vaio VGN-FZ-140E laptop in favor of xp pro SP2. Everything works other than my sound. I believe the onboard audio is Sigmatel High Def Audio. I have tried various drivers after hunting around online but they all state that there is no hardware installed.

In device manager it shows: Audio Codecs, Legacy Audio Drivers but nothing specific.

I installed the following windows updates as some have said they help before installing the drivers: KB835221: High Def Audio Driver Package and KB888111 also high def audio driver package. Neither helped the sigmatel drivers install.

I am at a loss. Can anyone help?

I looked on the Sony site, and the Drivers they have are all for Vista.

If you can find the Sigmatel model, you may be able to dig up an XP variant that will work.

I'm not sure about the update packages you downloaded. They may be Vista only as well.

They are supposed to be for xp but I don't know for sure. They installed no problem but didn't help.

one of the sigmatel drivers I tried came from a sony ftp site in a directory called xpdowngrade that some others who were having trouble found. It contained all drivers which worked except the audio drivers.

What does Dxdiag come up with when you do sound tests?

 

[Atvar]

No sound card was found.

Any BIOS options for enabling/disabling onboard sound?

I wouldn't think this would change from a simple format, but you never can tell sometimes.

If you go into Hardware Device Manager and delete the Sound devices, will Windows find it and try to install Drivers for it on boot-up?
You may want to give this a try, and even let it search the Net for Drivers as well if it gives you that option.

The BIOS on this thing literally gives you no options for anything so that isn't a fix unfortunately.

That's the thing, there is no option to uninstall anything under sound, video and game controllers. I have no idea what to do to fix this.

holy crap. I just looked under system devices and there is a pci device with an ! on it. pointed that to the drivers and it's finding all my audio hardware. I'll report back!

 

[wanderer27]

Whoo Hooo!

I think you've got it

 

[Atvar]

Well not so fast. So now I have sigmatel high definition audio codec under device manager but there is a ! on it and it says this device cannot start. This is after a reboot.

 

[wanderer27]

No Drivers were found for it?

 

[Atvar]

Found the problem...it was pointing to a .inf file in the windows system directory. I repointed to my unzipped sigmatel folder and the sound driver started just fine. I have sound. woooot

Good deal, glad you got it fixed.
