[SOLVED] E5540 update to 10.12.6 no audio

Hey guys, new to the hackintosh scene and I've gotten Sierra to run pretty well on the E5540. I followed this guide for everything: https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-precision-clover-guide/

 

I updated it to 10.12.6 afterwards and the audio doesn't work. Curiously, the audio didn't work before I updated it too.

 

I'm pretty much at a loss here. I've tried using other guides to get the audio working but in the end I've had to do a fresh reinstall multiple times after I screwed something up lol. I'm at the point where I'm thinking about just using VoodooHDA. Any help would be appreciated.

kextcache updated critical boot files, requesting launchd reboot

 

This is what I get when I input those commands.

 

Is it missing something important?

Yes for some reason AppleHDA_ALC292.kext is not showing up

Add this to /L*/E* replace the old one if it exists

run these commands, look for the kext in the output. Reboot when you see it or run until successful cache built

      sudo chmod -Rf 755 /L*/E*

      sudo chown -Rf 0:0 /L*/E*
      sudo touch -f /L*/E*
      sudo kextcache -Boot -U /
