Check 'Wake Reason' in system log when that happens.

Hi guys

I need your help with audio in EL C - booting Clover 3320 UEFI

Updated from Yosemite without problem but Audio is gone.

Using the DSDT from robertostudios with HDEF patch for ALC 292.

this is in my kextstat:

com.apple.iokit.IOAudioFamily (204.1)

com.apple.iokit.IOHDAFamily (272.50.31)

com.apple.driver.AppleHDAController (272.50.31)

com.apple.driver.AppleHDA (999.1.1fc1)

com.apple.driver.AppleHDAHardwareConfigDriver (272.50.31)

obviously ALC 292 kext is not loading, but why?

thanks for any pointers..

Re run:

Copy AppleHDA_ALC292.kext, and Codeccommander.kext to /System/Library/Extensions/

sudo touch /System/Library/Extensions/
sudo kextcache -boot -U /
reboot...

Everything works flawlessly, the only issue left is the finicky battery icon - sometimes it shows me the battery charge/icon, sometimes it doesn't. I'm currently using 1.60.3 of ACPIBatteryManager. Is this behavior to be expected?

thanks @robertostudios,

I did exactly what you suggested and now I get

com.apple.driver.AppleHDA (9267.0) instead of com.apple.driver.AppleHDA (999.1.1fc1)

AppleHDA_ALC292.kext is still not loaded (no entry in kextstat).

codeccommander is loaded.

where else can I look?

Jake Lo · November 2, 2015

com.apple.driver.AppleHDA (9267.0)

that means it's loaded, you won't see Apple_ALC292 in kextstat.

Did you use the clover-on-the-fly patches included in Robert's boot files?

Are you not getting audio?

Does it not show in preferences?

clickmikes · November 2, 2015

Hello Jake

I am using the config.plist from roberts boot files, they include the patches, right?

I dont have any audio and in preferences I can only see AirPlay speakers, no internal ones.

I can see internal mic, speaker, headphones, Line-in, HDMI-/DisplayPort-Output in my system information, but it shows no details at all.

thanks for more infomation...

Try booting without cache ( hit the spacebar and select it from the drop down)

Reboot to normal and see it audio works.

Need to verify cache is working. Clover patch on-the fly won't work unless cache is working properly.

How can I see if cache is loaded or not?

It seems that my AppleHDA is not included in the prelinked kernel.

When I do sudo kextcache -boot -U /

then I get this output:
