I had the same proble... and was SOLVED:
1-Download the propiate Audio driver from the VGN-SZ430N XP Support driver
2-Download Legroom Universal Extractor. Install the software.
3-Extract the driver using Univeral Extractor.
4-Browse through the extracted folder: TEMPEXEFOLDER; and then run the "setup" file from there.
4-It will install this way (you will see a quick splash screen of the Audio driver brand).
Drivers are available on the sony website. www.esupport.sony.com
Enter your model number vgn-sz430n and click on the driver button that appears in right-side window. I found them there.
ok, that is helpful info on your problem. First, note where you downloaded the audio driver. Then remove the driver that is presently installed. You should be able to do that through the device manager window. Then reboot your computer. It should "find" your card and want to install a driver when you reboot. Then choose the one you downloaded and install. You may need to reboot after this as well. If you still get a yellow exclamation point, you may have a hardware problem with your sound card which is not a cheap fix. Good luck.

I have already been to the site and downloaded the drivers for Win XP for the particular model. Even after that the sound car has not been installed. I get the question mark for them in the device manager. Please give me some alternative
