X201 Audio win xp

[gouldj]

Have just purchased a X201 which came with win 7 - for our sins we need to use it with Windows XP as all our garage diagnostic software is incompatible with win7 and the mechanics would probably not be any good using xp mode. - would confuse them and cause problems so easier to make the downgrade back to xp.

Every thing has installed apart from audio device. Can not get it to install - tried so many driver packages from intel and lenovo website none will work correctly.
In device manager it shows as unkown pci device - intel 3b56 rev 06 is the device information. would have thought it would install from chipset driver of HD graphics driver but nothing.

Really would appreciate some help here guys,
