Hi I am trying to get my Dell Optipliex 990 SFF to use the AppleHDA kext and was pretty sure I followed the steps correctly. However, I get a ton of sound assertion problems. Moreover, nothing is listed in the input/output section when I go to Apple > System Preferences > Sound. I have attached my codec info as well as my calculations for ConfigData. Any help would be greatly appreciated. (Using OS X 10.9.5)
Other things I did:
Patched DSDT to use layout 28
Deleted all other HDA references from S/L/E (Voodoo, disabler, etc)
