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 complete integration with the rest of the Mac OS X system.
Note: This is an advanced process and is highly dependent on your exact hardware configuration.
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!
