I don´t know if this drivers works on the chipset-integrated versions (ali/mvp4) of these chips. Simply give it a try and post your comments.

You need to unpack the driver with winrar. Then sipmly go to your system/hardware-tab chose your soundcard and click update driver. for i7-users: don´t let windows search for new drivers - instead point windows yourself to the directory. N-DEE :-)
