ALC885? Where are you found this codec? In BIOS? This is mistake of BIOS Developer, may be in test`s version Asus 1201N worked with ALC 885, but now it`s not so.
If you look at VoodooHDA dump or Linux codec dump, or Everest Device List in Windows, you will found 2 sound codec:
* ALC 269 - 10EC:0269 - onboard sound codec
* NVidia MCP7A - 10DE:0007 - HDMI sound codec
ALC 269 and AppleHDA incompatible, because AppleHDA not support some instruction of ALC 269
MCP7A don`t work with speakers and headphone output.
Than so we can try to patch VoodooHDA, or use Bluetooth Headphone, or use external soundcard compatible with Mac Os
, can you post your AppleHDA? And i`m interesting what version`s OS and kernel use you.
