No Sound after XP to Windows 7 Upgrade

Alright, so here's my problem.

I decided to upgrade to Windows 7 after using XP for what seemed like forever. I picked up a copy only to find out that I couldn't simply upgrade, rather I had to do a custom install. So I transferred my files to an external hard drive and proceeded to install 7. Everything went smoothly, I transferred over my original files and things were great. Until I realized my sound wasn't working.

I looked up solutions to my problem, most pointed towards downloading Realtek's new W7 driver. I followed some guides I found in my searches but after checking and rechecking my device manager, I saw that my sound driver wasn't updating.

Realizing my efforts weren't enough, I gave up and decided to revert to XP. I popped in my XP installation disc and rebooted. However, another issue came up. When choosing which partition to install the OS onto, my hard drive doesn't show up.

So now I'm stuck between a rock and a hard place. I'd much rather solve my sound issue, as I'm eager to try out Windows 7. But if that doesn't work out, I'll settle for a downgrade to XP.

I'm getting desperate. I'll take any help I can get. If you need any of my hardware info, just ask.

Welcome to seven forums you have sigmatel audio High definition with Vista drivers Avalible Sony eSupport - VGC-RB57G - Software Updates & Drivers You can try and install them in compatibility mode. Compatibility Mode Hope this will help . Fabe

I had tried that driver before, and I just did again to make sure. Both times I received this error. "This update is not intended for use with your computer model". I ran it under administrator in compatibility for Windows Vista (Service Pack 2).

Ok lets try this. Go to device manager>sound device>properties>details tab>drop down menu>hardware id. Copy and Paste the id string. And we'll see if we can find a driver fo you.

Check in Audio Properties and make sure that you have selected speakers for your default playback device..

In my playback menu, the field is empty. There's simply a note that says "No audio devices are installed."

Here is the driver for your Sony laptop -=> download

Went to the site but the download link it provided 404'd. Quick google search gave me a working download. Sadly I got this same error. "This update is not intended for use with your computer model."

Well it's defenitly Sigmatel, But in windows update cataloge it lists it as Realtek AC97 Audio controller. You can try the second from the bottom date 2/15.2008 version 6.10.5866.0 Still would have to use compatibility mode. Vista. click on add> then view basket>choose where to download it and download it. If this doesn't work we can try some of the Realtek drivers. Microsoft Update Catalog

Well the installation went fine, but I'm not sure it did much. Checked device manager, it doesn't look like it updated the driver. Still no sound.
