BleepingComputer.com: No audio devices

I have reformatted my old Sony VGN-FE38GP laptop with XP SP2 and everything is fine except for the fact that I can't get any sound.
In control panel it cannot even recognise any audio devices.
I have tried to load the relevant driver from sony support, but it won't load it and an error pops up to say the device supporting doesn't exist.
I have run bios and can't specifically see a menu for audio in there. I reset the bios and that did give me bios sounds (such as error).
But otherwise I have had no luck.
Tried lots of things...
Help please!!
