Hi, thanks for this thread.
Before 10.9.2 I had my sound working fine. HDMI audio too!
Now it seems that it has all changed, my microphone is no longer detected and HDMI audio is not working either.
I used your ALC269VB and changed the Layout ID to 28 to go into accordance of my DSDT, this allowed me to have my microphone again, but still no HDMI audio.
Is this because of the slight changes in 10.9.2?
I have tried to use the new Vanilla 10.9.2 AppleHDA and patch it with bcc9's script and then add in my layout26.xml.zlib, and info.plist. But still no HDMI audio
