Why should that matter? Patched AppleHDA.kext must be installed to /System/Library/Extensions.

Yes it is already installed to /System/Library/Extensions but either edit the original file or install edited file is still not work.

You can see quite clearly in your kextcache output that your audio kexts are damaged/corrupt:
