I don't think I quite understand the nature of my issue. I have Asus TUF Z270 Mark 2 with an ALC887.
On running the script, I get "Error: no IOReg/HDEF; BIOS/audio/disabled or ACPI problem".

I guess my first, general question is whether a solution to get my sound working is out there or not (yet)...

Alc887 audio works fine in 10.12, but after a few seconds if there is no audio playback, it is as if it were disconnected, it is heard in the speakers as before starting the operating system. After playing any sound returns to normal, To reproduce .... a few seconds later the same cycle ...help me please ...

in 10.11 ok
in 10.10 ok

See Post #1, No audio . . . Post to linked thread.
Thanks for your time. I remember that changing the definition to MacPro 5.1 does not happen, it works fine. But I will continue trying with iMac14.2 which is the one I believe closest to my configuration.

I thought it was some energy saving topic......

another question please. Is it ok to rebuild the kernel cache after patching AppleHDA.kext using the "cloverALC-120" script in the first post?

Thanks again
