Hi! I am trying to downgrade a sony vaio vgn-ar610e from vista to xp pro sp3.

I have succesfully installed Video, chipset, modem, media cards, LAN & WLAN. I am missing audio, built in webcam and hotkey functionality.

I can live without the hotkey, which I think it is going to be impossible to find any drivers for it but i need the audio and webcam.

I used EVEREST and found that my audio system actually has two chips:
Realtek ALC262 @ Intel 82801HBM ICH8M - High Definition Audio Controller
SigmaTel CXD9872AKD @ Intel 82801HBM ICH8M - High Definition Audio Controller

The webcam is automatically recognized by the os but when I try to use it I get a message saying the video device is currently in use, which is not true.

Anyway, I downloaded the realtek audio from the realtek webpage version 2.02, installed the driver and it passed with no yellow exclamation marks. I rebooted and when logging in I get "List index out of bounds (-1)" and no sound. I thought maybe I need the sigmatel driver. I tried at least 15 different drivers from different websites (hp, dell, even ftp://ftp.vaio-link.com/PUB/OS/XPDOW...RS/1_AUDIO.ZIP as someone suggested on this forum) and only one passed the installation without putting a yellow exclamation mark next to the driver. Great!, I said, but after rebooting, I got NO sound.

I reinstalled the OS thinking maybe the drivers are not working correctly because I tried with so many different drivers, so I did and still got the same problem. I did install microsoft UAA 1.0b just in case (SP3 should have UAA included) but no luck.

I am using a windows xp sp2 with sp3 and some intel drivers slipstreamed, otherwise i get the no hard disk drive found message during the windows xp install.

All programs that use sound system DO NOT complain about anything. WMP11 opens audio files without a problem but I get NO sound.

Does anybody have any ideas on this????
Should I just give up and stick to vista?? I really don´t want to...


Thank you for your help!!!!!!!!!

i tried googling for the drivers... not much usefull information came out... ... although i found someone suggesting these drivers on Treiber.de: Aktuelle Treiber für alle Systeme

Realtek ALC262 @ Intel 82801HBM ICH8M - High Definition Audio Controller:
ftp://ftp.vaio-link.com/PUB/OS/XPDOW...RS/1_AUDIO.ZIP

SigmaTel CXD9872AKD @ Intel 82801HBM ICH8M - High Definition Audio Controller:
ftp://ftp.vaio-link.com/PUB/OS/XPDOW...RS/3_AUDIO.ZIP


if these two drivers don't work, i would also suggest trying Windows Server 2003 Enterprise Edition SP2... actually it runs a bit faster than XP SP2 does, and it's a lot more stable, plus it has a bigger driver database than XP does. i've installed it on my rig (it's not a notebook, but still...) and it runs great , didn't have to install anything but the GFX card drivers ... the only downside to this option is that you have to tweak it a liitle bit to make it look like XP, and that there is no fast user switching service running in the background, so it looks a little bit less fancy (the "Welcome" screen doesn't appear when you boot up)... but there are lot's of tweaks on the web to make Server 2003 look and behave more like XP... there are also tweaks for playing games under Server 2003 (if you are worried that some games are not going to start or install)...
