If you used a pre-patched AppleHDA, then you'll have to repatch the kext since the update re-instate an unpatched vanilla version. If you use clover on-the-fly patch, then nothing will change but you need to make sure your cache has properly rebuilt (which it should have).

 

This assumes you updated from a previous Sierra version of course, not upgraded from an earlier release. If this is the case, you may have to adjust the on-the-fly patch.

no problem here either

- upgraded from 10.12.2 to 10.12.3  to 10.12.4 with no kext changes.

- upgrade to Clover 4049 (or later)

- using AppleHDA_ALC292.kext - with binary symbolic link to AppleHDA.kext and Clover on-the-fly patching.

No, I mean from which version OS X?

Make sure to update Clover as well.

I use clover on-the-fly patch method for audio on preview mac version.

I've updated from 10.12.2 and of-course also updated Clover to newest version 2.4k_r4049.

When I checked the system logs, has some as the following:

I am using AppleALC.kext (and Lilu.kext) for audio now. (so i can use the same kext on several of my hacks)

 

here is my list of custom kexts in /Library/Extensions

 

$ ls -d1L *

ACPIBatteryManager.kext

AlpsDell.kext

AppleALC.kext

FakePCIID.kext

FakePCIID_HD4600_HD4400.kext

FakePCIID_XHCIMux.kext

FakeSMC.kext

IntelMausiEthernet.kext

Lilu.kext

USB_PortInjector_M4800.kext

AlpsDell is the PS2/Trackpad kext by Dr Hurt. - more recent and does have some basic scroll gestures etc

yeah. i need to update my FakePCIID set to current levels. just haven't updated them lately.

I updated from the FakePCIID 1.2.x family to v 1.3.x and all is (still) good. Thanks for reminding me to do that Jake. 

 

@tudt949 - seems like your audio kext has an issue with the MacOS binary. check the symbolic link. you can remove the link and recreate it if its messed up.  Note: I moved to using the AppleALC.kext instead the AppleHDA_ALC292.kext, as this alternate kext supports a variety of codecs ALC292, ALC293, and a variety of others.
