Yes, I had subsequently found that information in the guide and my next post was that result:
"I found this at AppleHDA.kext/Contents/PlugIns/AppleHDAHardwareConfigDriver.kext/Contents/Info.plist
(Which is the proper codecID for alc288):
<key>IOKitPersonalities</key>
<dict>
<key>HDA Hardware Config Resource</key>
<dict>
<key>CFBundleIdentifier</key>
<string>com.apple.driver.AppleHDAHardwareConfigDri ver</string>
<key>HDAConfigDefault</key>
<array>
<dict>
<key>AFGLowPowerState</key>
<data>
AQAAAA==
</data>
<key>CodecID</key>
<integer>283902600</integer>
<key>ConfigData</key>

</data>
<key>FuncGroup</key>
<integer>1</integer>
<key>LayoutID</key>
<integer>3</integer>
</dict>
Is it safe to say AppleHDA is in fact using the correct layout-id (3)?"
The info above indicates layout-id 3 for 283902600, which is 0x10ec0288, or Realtek ALC288.
There were several codecs listed in this section, but this was the first in the list. Should I edit the info.plist and remove the unneeded codec references, or is that not necessary?
I always remove the extra codecs since the others are not needed and just cause confusion over the applicability of the patched AppleHDA. But it will have no material effect.
