Thanks Voodoo Team
ASUS P5B motherboard (vanilla)
Has AD1988 (not B)
Earlier it used to work only with AzaliaAudio
With VoodooHDA, speakers work, I only use stereo speakers, Cant change the number of speakers to more than two in Preferences.
The Analog Out is recognised as "Unknown"
Digital Out gets recognized in Sound Preference Panel
Mic in is recognized but doesn't work (hopefully work in progress)
The VoodooHDA.PrefPane just crashes when run ("Cant map memory" error) Was not using the kext bundled with prefpane. It works if the bundled one is used
And it works from /Extra in EFI partition nicely, it needs IOAudioFamily.kext and OSvKernDSPLib.kext installed in /Extra to satisfy dependencies
