Oke, i have the same problem, doesn't recognize the multimedia audio controller
Before I installed a fresh windows xp on my pc, i runned sandra (something like belarc) and it said under multimedia audio controller:
intel 82801eb ich5 ac '97
as my motherboard is a soltek SL-86MIP-L, i installed the driver for audio from the official website.
But still no luck, then after reading all of these posts

i released that i had to install the intel chipset driver first(also downloaded it from the official site)
Si I did and installed the audio driver again, still no luck.
Then i installed 3 other audio drivers from 3 different sites and still no luck.
I hope you can help me
