I am using Toshiba Satellite U400-ST6301 laptop. It is running Windows XP Pro SP3Operating system and has Conexant High Definition SmartAudio 221 installed in my laptop. I am looking for the drivers, especially the Audio Drivers of Toshiba Satellite U400-ST6301 laptop. So does anyone know where I can find the following drivers for my Windows XP Service Pack 2 running laptop? If anyone have got any idea relating the following issue of mine, please post your suggestions. They will be appreciated. Thank you.
