Haswell/8 Series/Socket 1150 - HD4600/AMD/Nvidia HDMI Audio

Update v2.2: 2/25/14 - 10.9.2/Mavericks HD4600/HD4000/HD3000 Framebuffer Edit Scripts
Update v2.1: 10/23/13 - Mavericks/10.9 and HD7xxx supported
Update v2.0: 10/14/13 - HDMIx2 and DVI2HDMI audio working
Note: v1 Archive: Haswell HDMI Audio (v1 Archive)

OS X HDMI audio for Haswell/HD4600 systems with either: 1. HDMI audio edited dsdt or 2. the Haswell HDMI audio ssdt. Both techniques enable native Haswell graphics power management. Haswell HDMI audio is not native; AppleHDA.kext and AppleIntelFramebufferAzul.kext require edits (Note 1 and 2, below) Credit, PikeRAlpha for both fixes.
