    Sound driver Windows 8 UEFI boot (no bios emulation) Mac.


    I recently installed windows 8 on my MacBookPro with UEFI support, but I can't enable audio. I know that apple use BIOS emulation for windows and the assign different Hardware ID's for devices.

    With BIOS emulation ID is:


    Without emulation ID is:


    I tried changing inf file and it detected the required audio card driver, but it shows that device cannot start. It's Cirrus Audio CS4206B (AB83) sound card, but without emulation it shows it as intel audio card. It would be easier to get back to bootcamp, but I really want to make this work.

    Thank you in advance.
