Demystifying HDMI Audio Part 1: Requirements
Enabling HDMI audio via AppleHDA in Mac OS X 10.6.x is comprised of four guides:
Snow Leopard HDMI Audio - Part 1: Requirements
Snow Leopard HDMI Audio - Part 2: DSDT Edits
Snow Leopard HDMI Audio - Part 3a: Kext Edits for AMD 5xxx
Snow Leopard HDMI Audio - Part 3b: Kext Edits for NVIDIA 4xx
Enjoying HDMI audio + video on most graphics card and motherboard configurations is documented using the replacement audio driver VoodooHDA. Enabling the supplied AppleHDA is something of a challenge but offers significant benefits including native support, high quality audio and integration with the rest of the Mac OS X operating system.
Advanced DSDT & Kext Editing
Note: This is an advanced process and is highly dependent on your exact hardware configuration.
Enabling HDMI audio in Mac OS X 10.6.x is comprised of three parts:
Part 1: HDMI Audio Requirements
Determines if your system is capable of HDMI audio
Part 2: HDMI Audio DSDT Edits
Configures your motherboard for HDMI audio
Part 3: HDMI Audio Kext Edits
Customizes Mac OS X for your graphics card
After all this work, how do you know if you have successfully enabled HDMI Audio in Mac OS X? Select System Preferences/Sound/Output. Look for HDMI, select HDMI as your audio output device and enjoy!
This guide applies to Mac OS X 10.6.5, 10.6.6 and 10.6.7 only. The Early 2011 MacBookPro 10.6.7 release, Early 2011 iMac release and Mac OS X 10.7 are not considered.

If you answered no to one or more question, your system is not configured correctly for HDMI audio. Before proceeding, please update your your system with the appropriate solutions.
Examples of required HDMI Audio capabilities are presented in the following HDMI Audio Requirement Verification pdf.

Your system may be capable of native Snow Leopard HDMI Audio if you answered yes to all questions. There are no guarantees. A system that produces HDMI audio for someone else may not work for you. Similarly, your system may work even if others are unsuccessful.
