Audio work previously from Snow Leopard to El Capitan with Chameleon bootloader and Clover generic. Now with Sierra fresh install and Clover generic I have a Efi partition, before Efi was on Sierra partition-that's the difference.

Finaly reinstall Sierra with manual install Clover on Legacy mode. Clover Legacy mode on MultiBeast automatically install on ESP. Same no audio device, files attached. Good thing now DPCIManager is working.

EDIT: I got stereo now working, but may need some help for the Audio-MIDI-Setup - I guess, I have to use different ports for the three 5.1 cables: black, green, orange - should they go anywhere else?




---Description of audio problem

Fresh install of Sierra on 500GB HDD, Multibeast, Clover Legacy 3766, System ID as iMac 12,2
Rear Audio with 6x 3,5mm inputs for Audio, micro doesn't seem to work, (it worked minutes ago on El Capitan with identical installation ALC889 + Optional 5.1!)
BUT the FRONT Head-Stereo works !!! (this is part of a 2x USB 2, 2x USB3 and Micro/Headstereo combo connected with one big cable to the motherboard). Why does this work, but the Audio-out with three coloured cables, black, green and orange doesn't work for 5.1

---OS X version/motherboard model/BIOS version/processor/graphics

---MultiBeast/Audio Selections
Multibeast for Sierra, Realtek ALC889, +Optional 5.1

---Terminal/Shell/File/Export Text As. . . (if Terminal script run)
no idea what that means, not applicable

after installing ShowAllFiles I found this AppleHDA.kext in S/L/E is from Dec. 23, 2016, 8:33 with 4MB (what should I do with it?)
