Windows XP

Windows XP recognizes the "Ensoniq AudioPCI ES1370" device (that is emulated by QEMU) automatically.

Windows Vista

TBD

Windows 7

"Intel 82801AA AC97" emulation works with Windows 7. Windows only detects presence of "Multimedia Audio Controller", but the driver can be loaded by the standard procedure in windows : "update driver" then let windows choose the right driver on internet.

"ENSONIQ AudioPCI ES1370" emulation is also recognised by windows by the same process, but the driver crash regulary.
