Sound problem on win XP X64

Hi,
recently got win xp X64 professoinal installed on my rig, every thing is ok, except the onboard sound which i cannot install from mobo CD, in device manager one of the BUS drivers is faulty. i removed it and tried again but nothing happend .

what should i do, how ever it works great on 32 bit OS.

Thanks for any help

when i looked at the trial releases of the xp 64 there was an issue with not having many compatible drivers out yet, tho time has passed and im sure there have been many additions to the list it may very well be that there are no compatible drivers yet.

i suggest looking for some as if you didnt know that already lol
