The patch and kext work on my HP431, however I have to edit this patch following DSDTEditor format because I use DSDTEditor. Now sound works far better than voodoohda. Thanks for the patch :mrgreen:

Uploading it now. adding dsdt.dsl which you can see the patch inserted.

After updating from 10.9.0 to 10.9.5, the sound stop working. Had to use voodoohda for a while. Then I read somewhere that AppleHPET.kext had to be restored too. So I reinstalled this AppleHDA.kext and copy AppleHPET.kext from /Backup/Kext/ to /Sytem/Library/Extensions, repair permissions and rebuild kernel cache, and voila, the sound is back! Yay...

edit: sorry, my bad. AppleHPET.kext maybe is not the cause. I have to boot using -f in order to get AppleHDA to work.
