Gateway Audio Issues

Hello,
I've been working on trying to restore sound on my friend's laptop that I'm currently using. I checked the device manager, and there were no apparent issues. I've checked all simple explinations for the problem and there's no obvious issue (sound is not muted or lowered, no external audio buttons hit). I've even tried to reinstall her audio drivers, which then provoked an exclamation mark under the secondary HD audio mark on the device management screen. I know she's using Vista 64, there's an AMD Turion x2 sticker on the laptop.

I tried checking the microsoft catalog and was able to download an AMD 64 build driver, but it comes via .cab and I honestly don't know how to use that file. Trying to "update driver" and pointing it towards that folder does nothing.

I've checked the services under administration tools, and Windows Audio and the other Win Audio listing are both set to Running/Automatic. Tried to even restart the services.

Only things I've been unable to test are if it's just the speakers or if it's all audio as there are no handy external speakers or a headset of an sort, and I've also seen some reference to registary problems, but I'm not sure where to start looking within the registary.

What can I do to get her sound working again? I will try to list as much of her system specs below:

Gateway MD2641U
AMD Turion X2 Dual-Core Mobile RM-72 2.10GHz
3.00 GB Ram
Vista 64-Bit Operating System
Under "Sound, Video and Game Controllers"
Conexant High Definition SmartAudio 221 - No Errors
High Definition Audio Device - Error - Code 19 Windows cannot start this hardware device because it's configuration information (in the registary) is incomplete or damaged.

Only other issue I see in the Device Manager is under Network Adapters:
Microsoft 6to4 Adapter - Code 31

Thanks a ton for your time guys and gals,

1. Registry issue - download/install/run http://www.piriform.com/ccleaner
In the left column click on Registry and then click on the Scan button.
After you clean the registry, click on Cleaner in the left column, then click on the Analyze button.
Now you can clean the temp folders.

Let's see if any of these items get fixed now or not.

Recommend deleting the Conexant High Def SmartAudio driver, then reboot.
Does Windows recreate it and if so what does it say?

Do you have a Gateway MD2641U or a Gateway MD2614U ?

Do you have an external device connected to the laptop that would make use of a sound driver?

Can you post an image of the Device Manager?

I see no device issues now.

FYI - As for the .cab file you mentioned earlier, with the Windows Explorer treat the file like folder. Double click on the file and it should open another window showing all the files inside the .cab. It's kind of like a .zip file.

In the Control Panel under Sound, what do you see?
