Hi! I've been building hackintoshes off and on for a while now, but never have posted to this forum. I'm still consider myself a newbie. First of all, I'd like to thank Kogen Mantis and everyone else for all their hard work, after reading through this thread I'm able to get my T420 up and running pretty good! I spent all evening yesterday trying to fix one issue though: my sound doesn't work.
It looks like I'm in the same boat as espamac where I'm trying to install 10.8.2 but have a Conexant 20672. I've gotten sound to work exactly once, and this was after running Kext Wizard to clean up permissions and caches on both extra and /s/l/e. After I rebooted, the sound never came back.
I always see these entries in the syslog:
Mar 17 20:31:10 localhost kernel: Kext com.apple.driver.AppleHDAController - library kext com.apple.iokit.IOGraphicsFamily not found.
Mar 17 20:31:10 localhost kernel: Can't load kext com.apple.driver.AppleHDAController - failed to resolve library dependencies.
Mar 17 20:31:10 localhost kernel: Kext com.apple.driver.AppleHDAController failed to load (0xdc00800e).
Mar 17 20:31:10 localhost kernel: Failed to load kext com.apple.driver.AppleHDAController (error 0xdc00800e).

Mar 17 20:31:12 Dougs-MacBook-Pro kernel: Sound assertion "!fProvider->open ( this )" failed in AppleHDAController at line 355 goto Exit
I've tried various DSTS edits, including the one above along with the AppleHDA.kext in post #83
Not sure if I'm doing something wrong or what. But I'm willing to try more options if anyone has an idea.
Here's some more info:
16 gb ram.
OSX installed in 2nd hard drive installed in the optical bay
Audio: Name = Conexant 20672 SmartAduio HD: VEN_14F1 DEV_506E
Also, I was wondering if anyone else had issues with graphical artifacts showing up every once in awhile? Also, about 25% of the time when I boot, it'll boot into an ugly grey screen with spikey lines. I can fix the graphic artifacts by lowering the resolution and then raising it again, and usually the grey screen goes away on the next boot.
Thanks again for your help!!! I've attached the DarwinDumperReports
