Quick Fix: 200 Series/Kaby Lake and X299 Audio
Onboard and/or HD 6x0 HDMI Audio
The 200 Series/Kaby Lake HD Audio Controller is currently not supported in released versions of macOS (developer builds. excepted). Symptoms are audio devices present, iTunes not playing and no sound.
Fix: Patch the Skylake Audio Controller (0xa170) for Kaby Lake and X299 (0xa2fo)
This fix is temporary; required until macOS/AppleHDA.kext natively supports 200 Series/X299 Audio.
Supports 10.12.6, 10.12.5 and 10.12.4.
