Ok great, I presume that I don't need to install the HDAEnabler anymore now?
So, if I'm correct I install the 10.11.1 ALC662 kext from your main thread and repair permissions (Kext Wizard and Mickeys tool?) and then just drop the new config and DSDT in EFI/Clover. Reboot and enjoy the sound!
Sorry, still getting used to all this, but trying to learn fast.
