This solution did not involve a patch (so no 'repatch') -- it was a rollback. Would involve determining the actual problem and patching the current kext to fix it.

Maybe you need to also rollback IOAccelerator*.kext and/or IOGraphicsFamily.kext.

These kexts are typically tightly coupled. It is not surprising they crash when you mix different versions of them. What is surprising is when they continue to work when mixed...

Tested. IOAccelerator*.kext rollback was needed. HDMI is working, with no sound.
