HDMI Audio + Video can be enabled on Mac OS X for most graphics card and motherboard configurations without much hassle using the replacement audio driver VoodooHDA. Using the supplied AppleHDA.kext for HDMI audio is something of a challenge, but provides numerous benefits including native Mac OS X support, high quality digital surround audio and overall system integration.
Over the past few months, toleda has been exploring and experimenting using different methods, and has come up with what we think is a pretty definitive series of guides on the subject. Please note that this is an advanced process and is highly dependent on your exact hardware configuration.
Enabling HDMI audio via AppleHDA in Mac OS X 10.6.x is comprised of four guides:
- Requirements - Determines if your system is capable of HDMI audio.
- DSDT Edits - Configures your motherboard for HDMI audio.
- Kext Edits for AMD 5xxx - Customizes Mac OS X for your AMD 5xxx graphics card.
- Kext Edits for NVIDIA 4xx - Customizes Mac OS X for your NVIDIA 4xx graphics card.
