Not certain what your motherboard is, but this old Foxconn 760GXK8MC also has the ADI AD1888 sound chip on it and Windows 7 Home Premium 'sees' it as a REALTEK AC97 compatible.... which DOES
sorta work, but ONLY if you plug your speakers into the blue external input jack - NOT the green audio out!!
And it actually does work!! Hello-o-o-o.....
(go figure...

).
Heck.... As long as this thing makes sound - I really don't care where it plugs in.
It's just for 'play', anyway..........
