Thanks and credits to: THe KiNG, stickpin, Kabyl, karaakeha1, MadTux, Taruga, OcciJano, MaLd0n, toleda, janek202, RevoGirl and everyone (will be listed if I remember) who published tools, kexts, information, and hints. Note: I removed all patched binary kexts. Sorry for this action because I want to clean up this post. Date: 2011, August 04. Knowledge & How to: [HOW TO] Patch AppleHDA - Knowledge Base by THe KiNG, this's useful. Please read all of them to get some idea for you. How to patch AppleHDA.kext from 10.5.2 and above, Ii is a little bit hard, but is fun. by MadTux [How To] Pinconfig for Linux users by Master Chief Audio Device Technologies for Windows from Microsoft Pin Configuration Guidelines for High Definition Audio Devices from Microsoft Legacy AppleHDA for BOOT-132 by stickpin [How TO] 5.1 Surround Sound by consolation [How to] Have sound on all of your speakers by macgirl How to get 5.1 audio out of AAC-surround-encoded audio Editing custom personalities for ATI Radeon HD[45]{censored} by bcc9 DSDTs: DSDT: trick retail drivers by changing "device-id" (e.g USB)by zhell ACPI (DSDT) Patcher for BIOS and AML by koalala DSDT Patcher by fassl DSDT fixes for Gigabyte boards by iSoprano DSDT - Vanilla Speedstep - Remove _cst errors for MB without C-states by FormerlyKnownAs HDEF_DSDT-Patcher_Gigabyte go to post #951 Installing legacy kext, and HDAEnabler.kext to whare? 1) legacy kext(s) and HDAEnabler.kext can be installed into /Extra/Extensions, /Extra/Extensions.mkext, or /System/Library/Extensions. 2) LegacyHDA.kext contains only info.plist so it has to work with AppleHDA.kext. 4) HDAEnabler.kext is not required if you are using DSDT.aml with HDEF injection. 5) layout-id in DSDT or HDAEnabler.kext must be matched to LayoutID in info.plists of LegacyHDA.kext or AppleHDA.kext. 6) To avoid popping sound is to be MacPro because my work based on MacPro setting. How to enabler sound: there are three ways as I've known. Use only one that works for you. 1) Using HDAEnabler.kext. 2) Using DSDT with HDEF injection. 3) Using EFI string. How to get sound working: there are many ways. 1) vanilla AppleHDA.kext + LegacyHDA.kext + HDAEnabler.kext (or DSDT w/ HDEF injection) for ALC889a/ALC885 2) vanilla AppleHDA.kext + LegacyHDA.kext + DSDT w/ HDEF injections and HDAU (HDMI audio) injection for ALC889a/ALC885 plus nVidia GT220* 3) bin patched AppleHDA.kext for ALC### only + LegacyHDA.kext for ALC### + HDAEnabler.kext (or DSDT w/ HDEF injection) 4) bin patched AppleHDA.kext for ALC### plus nVidia GT240* + LegacyHDA.kext for ALC### + DSDT w/ HDEF & HDAU injections 5) bin patched AppleHDA.kext & edited info.plists for ALC### + HDAEnabler.kext (or DSDT w/ HDEF injection) 6) bin patched AppleHDA.kext & edited info.plists for ALC### plus nVidia GT240* + DSDT w/ HDEF & HDAU injections 7) bin patched AppleHDA.kext & edited info.plists for ALC### only plus nVidia GT220* + DSDT w/ HDEF & HDAU injections 8) ALC### disabled plus nVidia GT220*: vanilla AppleHDA.kext + DSDT w/ HDAU injection 9) ALC### disabled plus nVidia GT240*: bin pathced AppleHDA.kext for nVidia GT240 only + DSDT w/ HDAU injection HDMI: all links seem to be broken and I will update them as much as I can. There are two methods to get audio via an HDMI cable. 1). For nVidia graphic cards that have a S/PDIF connector , read Post #759. 2). For a graphic card that has a built-in audio chip, see Post #760. Update: thanks to toleda for telling me how to add "connector-type" in DSDT so that I can get HDMI audio working again. -- for GT240M -- HDMI audio by Jingu -- for GTX480 -- need to read previous posts by zzebulonn -- for Sapphire vapor-x HD 5770 -- HDMI audio by VCH888 USB Audio: C-Media CM6206 Enabler for Mac OS X v2.1 In case of no sound after waking up from sleep, see https://discussions.apple.com/thread/5541299?start=90&tstart=0 for patching AppleHDA, OS X 10.10 to edit script from line of cat /tmp/patch|grep -A 500 "<key>IOClass</key>" to line to cat /tmp/patch|grep -A 700 "<key>IOClass</key>" Added for H87M-HD3: Outputs are similar to 945GCM-S2L's ALC662.
