I followed your post and I put the AppleHDA_IDT.kext in the /L/E and followed you instructions on repairing the permissions. I also get the following:

When rebuilding your cache, if you're getting:
Child process /usr/sbin/kextcache[625] exited with status 77.
Error 107 rebuilding /System/Library/PrelinkedKernels/prelinkedkernel

repeat the sudo touch + sudo kextcache commands.

If the problem persists, remove the kernel cache files entirely before rebuilding the cache:

sudo rm -Rf /S*/L*/PrelinkedKernels
sudo rm -Rf /S*/L*/Caches/com.apple.kext.caches
