According to nuschnuschi here, it is but loses audio after sleep.

 

Right.

 

VoodooHDA 2.8.5 - Headphone jack (mic combo) works but Internal Speaker doesn't work after wake up from sleep.

 

Patched AppleHDA - Internal Speaker works after wake up with EAPDfix.kext. but headphone jack doesn't work(only white noise).

 

I'm still looking for a solution.

 

Thx.

But I was already in use.

 

I just wanted to try to install an AppleHDA.

 

I downloaded it from this topic. I also tried to patch AppleHDA my self but result was same.

After rebuild DSDT and re-install AppleHDA, AppleHDADisabler, VoodooHDA 2.8.5 and EAPDFix 1.5b3, 

Now Internal Speaker is working after wakeup from sleep. Also Headphone jack works.

 

Sorry but I'm not sure about what was a cause of problem.

Wouldn't AppleHDA gets disabled with AppleHDADisabler and only voodoohda works?

AppleHDADisabler disables some functions of AppleHDA.kext but it allows to load IOHDAFamily and AppleHDAController.

 

VoodooHDA works without AppleHDA, Disabler and EAPDFIX.

but internal speaker won't work after wakeup from sleep.

 

if I installed those kexts same time then Internal Speaker just works fine before/after sleep.

I need to investigate about them more.
