AIO Complete Guide to Patch AppleHDA for Your Codec

Hello Everyone,

This guide will explain how to edit AppleHDA to properly enable audio support for Mac. Patching AppleHDA is much tricky and consumes lots of time and experience .

This is a complete AppleHDA patching guide for the Audio codec in the Desktop’s (but theory works for NoteBook too).I’m writing this guide based on my knowledge and experience gained myself doing so many patches and details from the web from more than a year. Hoping this could help many people looking to patch their AppleHDA by themselves. I did my best to make this as simple and easy as possible and Noob proof.

Also I don’t take credit for all this information entirely except for appreciation on writing this guide.Specially EmlyDinesh and Mirone who helped me in each and every steps .

The credit will go for all these people: EmlyDinesh, Mirone, king, Master Chief, RevoGirl, toleda, bcc9, TimeWalker and many others who contributed to AppleHDA patching.

I’m using the Audio codec ALC887-VD audio which i’ve in my MOBO:::GA-H61M-D2H  &  Asus H61M-D  for explaining the process.

Hope everyone can find this easy and helpful. !!Lets get started!!

The Seven Chapters are:

  1. GETTING CODEC INFORMATION.
  2. CALCULATING PINCONFIGURATION AND VERB COMMANDS.
  3. CALCULATING PATHMAPS .
  4. PATCHING XML  ( PATHMAPS AND LAYOUT )FILES.
  5. AppleHDA BINARY PATCHING.

Preface:

Prior to attempting to begin patching AppleHDA for your configuration read the guide in its entirety. Doing so should allow you to see what parts or sections that you may not understand which will allow you to do research so that you are able to understand in your own way.
