Toleda has released two new patched AppleHDA audio drivers designed to optimize any motherboard with the Realtek ALC 889 or Realtek ALC 892 audio codecs. This is the best and most complete support that we've ever seen. The new one-kext solution supports most Mac OS X Lion analog and digital audio capabilities. It is designed to be an alternate or replacement for the combination of both AppleHDA Rollback and ALC8xxHDA. Proper DSDT edits are still required. One unique feature of the driver is the ability to alternate between 2 different layout-ids, enabling either most onboard devices, or HDMI audio with slightly limited onboard devices. For example, in order to get HD 3000 HDMI audio, you will need to change your layout id in your DSDT's HDEF section to 389. The default 889, used in the DSDT Database, will enable the optimal onboard analog and digital options. Download AppleHDA for Realtek ALC 889 Download AppleHDA for Realtek ALC 892 source

You should definitely read through it, but here’s the gist for movies that contain AC3 audio files: Install a copy of the free Perian QuickTime plug-in on your Mac. String an optical cable between your Mac and a compatible receiver. Launch Audio Midi Setup (found in the Utilities folder) and in the audio output area select Digital Out from the Source pop-up menu and 48000.0Hz and 2ch–16-bit in the Format area. Launch the Terminal app and enter  defaults write com.cod3r.a52codec attemptPassthrough 1  Press Return. If iTunes is running, quit and relaunch it. Locate the movie you want to view, and play it with iTunes’ Volume slider set to its highest level. Also be sure that the equalizer is off. Place your cursor over the movie so that the on-screen controls appear, click on the small bubble icon, and choose the surround sound track. With a little luck, iTunes should now play the movie with surround-sound audio. source:

A: You must  reinstall  those hacked kexts, because the update overwrite the vanilla hacked applehda kexts. Should even happens that the update doesn't overwrite the old applehda kext driver, so in this case, you don't need to reinstall. Q: I'm experiencing pop sound, how can I solve this?
