Your IOReg shows next to nothing under device HDEF so, indeed you have no audio enabled. Assuming there's nothing in BIOS to block this, you should consider implementing the HPET IRQ patch. That should fix your audio issues.



Did you fix your config conflicts regarding codec layout id? Because the config you posted in port #1 showed:

  1. codec layout 11 being injected in Device Properties
  2. codec layout 3 being injected through NVRAM boot arg



You need to decide on one method or the other, not both and opt for the correct layout of course!
