Hello Rehabman, kudos for all of your hardworks!

Did you try binary patch solution to wake the sound after sleep instead with kext? (i blogged months ago with original link attached). I know this not an issue / completely unrelated with this repo, sorry. Hope you found it working / useful for your next project 😄 (Tried without afail with smbios macpro6)

Thanks for the pointer...

I tested it on my Lenovo u430: Added the patches to my config.plist, removed CodecCommander.kext.

It does not work. Audio is lost after sleep.

I may take a more detailed look at the patch to determine what it is trying to do in an effort to determine why people think this fixes the EAPD issue.

My guess is that this is a fix not for EAPD, but rather a fix to reset the codec upon wake. It will help where CodecCommander is used for that reason, but not for the EAPD reason. Realize that CodecCommander is not single purpose, and, in fact, is used to fix several different problems.
