What I found out is: there's no x64 driver for both AC'97 and ES1370 for Windows. 64bit Chipsets would have no AC'97, so there is only the Realtek driver which doesn't work well. And ES1370 is a very, very old audio chip which is probably only supported for legacy reasons but only in the 32bit versions of Windows. In the link from comment #4, the 32bit version of Windows was used.

See http://www.virtualbox.org/ticket/5332 which is essentially the same problem for VirtualBox.

Can you confirm that Windows Update finds drivers for x32 but not for x64 versions of Windows?
