There is a solution for all people with 3k bios and no audio. You can downgrade Bios using this guide: http://vip.asus.com/forum/view.aspx...board_id=1&model=P8P67 DELUXE&page=2&count=11
I have tested it myself and gone from 3301 to 2303 within few minutes using Windows. My mobo is P8P67. I guess it is 100% safe if you know what you are doing. Good luck, but I do not take any responsibility for any damage.
For Lion, MultiBeast 4.6.1/Patched AppleHDA/ALC892.My Mobo chipset is ALC892 sound of the DH61AG.
With the info provided, no way to know what is wrong.The sound is not recognized..
This patched AppleHDA is only available in the lion?
