My original Asus P8P67 pro Hackintosh guide was not very clear on how to get your P8P67 pro based hackintosh’s audio working. Here is a much simpler guide on P8P67 pro hackintosh audio:
Part A ) Install your hackintosh using this guide: http://understandingexistence.net/2012/08/28/asus-p8p67-pro-hackintosh-guide/
Part B ) Once OS X Mountain Lion 10.8.0 is installed:
1.) Download and install the latest Mountain Lion MultiBeast from tonymacx86.com
2.) Run MultiBeast. Select and install non DSDT drivers for ALC 892. Reboot.
3.) Mountain Lion 10.8.2 Update: Upgrade your hackintosh to the latest Mountain Lion 10.8.2 from the app store. The 10.8.2 update will break your hackintosh audio but you can easily fix that simply by repeating step 2.
Done. Enjoy your hackintosh.
