so i tried to find some information in OS X and after a while i stumbled upon a document "Info.plist", to which i was pointed by OS X's build-in hardware info-utility, somehwere in /System/Library/Extensions/AppleHDA.kext/....
http://nopaste.org/p/aRCCwdDXqb
also some information right out of the apple tool, eventhough i don't think that it's worth anything: Intel High Definition Audio: Device ID: 0x10DECB79
This is likely a different chip.

A quick google shows that the vendor ID is Cirrus Logic. The Boot Camp driver set does include installers for Cirrus audio cards. I don't have Windows installed on here, so I can't check to see if it is indeed the Cirrus drivers that get installed. What can be done to facilitate the implementation of this codec?
I guess it's CS4206 codec. CS4207 has a different id.
out of the Info.plist: <string>Cirrus Logic CS4206</string> <key>CodecID</key>
And that's it.
so again: if i can, i'd love to help.
I created the support for for Cirrus Logic chips (cs420x only). It's included in sound-unstable tree. Grab the alsa-driver-unstable snapshot from ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-unstable-snapshot.tar.gz
Let me know if it works or not.
Also, prepare to install hda-verb program. I'd like to confirm the behavior of the codec, and I'll ask it later once after the driver works somehow.
thanks,
Takashi
