After I remove SleepEnable.kext and AppleHDA.kext, then update from 10.7.2 Iatkos to 10.7.3 successfully. I started to install SleepEnabler.kext for 10.7.3 by this link SleepEnabler.kext.10.7.x.zip - xnu-sleep-enabler - SleepEnabler for 10.6.x / 10.7.x updated for 10.7.3 - A kernel extension for the latest Apple Darwin XNU kernel, re-enabling sleep for generic x86 computers. - Google Project Hosting however when i used Kext Wizard to install it, this Kext was sink and unavailable to install, manually is doesn't work either. Anyone can tell me why sometime the kext was sink and can't be installed and any suggestion.
The second problem come from AppleHDA.kext (ALC 889). After i install the kext of ALC889 for 10.7.3 supporting in this forum, my speaker still keep silent. Please help me to find the suitable kext which is works on 10.7.3.
Thanks in advance.
