No, Night i haven't but I am using an ALS4000 sound card cause I couldn't make onboard audio work. Any Idea for make it works?

ftp://ftp.biostar-usa.com/drivers/Audio/VT8235_4.EXE See how this works for you. Abit AN8 Socket 939 AMD64 3000+ -1.8Ghz @ 2.0Ghz Corsair 1Gig 2x512 MSI Radeon x800 PCI-E 390@445-700@1000 Seagate 160Gig SATA Antec TrueControle 2.0 550 Watts

If these one's don't work, let me know HOW they don't work. Still no sound? Error? Funny noises? This should be your Motherboard: http://www.biostar-usa.com/mbdetails.asp?model=u8668+grand It matches everything you said, the model number and the Chipset.

Yes I know it matches, but its still no sound at all, well before I reinstaled Windows XP it had sound, of the onboard sound system of course but now there's no sound, even I've downloaded everything in the biostar site, reload windows many, many times but its still doesn't work, so now I' ve installed an ALS4000 sound card and works great. I think the mobo has suffer some damage or something. Once again... any Ideas?

So? you find something else?
