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:

out of the Info.plist:
<string>Cirrus Logic CS4206</string>                          
<key>CodecID</key>


so again: if i can, i'd love to help.


thanks a lot
