5/2/12 - An update is available for this AppleHDA.kext; see 889_Lion_AppleHDA
The ALC889 edited Lion AppleHDA.kext is available for Lion 10.7.2 and motherboards with the Realtek ALC889 audio codec . Supports most Lion analog and digital audio capabilities. Users interested in capabilities beyond standard on board audio should consider this option, includes HDMi audio (discrete and HD3000 integrated), front panel audio and more. This kext supports two layout ids: layout_id 889 for full 889 analog audio on any 889 motherboard with or without discrete graphics card HDMI audio (Note 1) and layout_id 389 for 889 analog audio on a 889 Sandy Bridge motherboard with HD3000 HDMI audio (Note 2)

10.7.2 Nvidia HDMI Audio Issue
If your system boots to a black screen or KPs after installing this kext, three choices:
1. Restore Original AppleHDA
a. Reboot with GraphicsEnabler=No
b. Install your AppleHDA.kext backup
c. See this thread noted below
2. Install Encoded Digital Audio AppleHDA binary per read_me_first instructions
a. Reboot with GraphicsEnabler=No
b. Install the Encoded Digital Audio AppleHDA.kext
c. If problem remains, see this thread noted below
3. See this thread (TBA)
Notes
1. HDMI audio dsdt and kext edits required. More info:http://www.tonymacx86.com/viewtopic.php?f=162&t=31664
2. HD3000 HDMI audio dsdt and kext edits required.
3. Use Applications/Utilities/Audio MIDI Setup to configure analog 5.1 surround sound with 3 Line Outs
4. Requires Platforms.xml edit, adds Grey LineOut and deletes SPDIFOut. Use Audio MIDI Setup to configure analog 7.1 surround sound with 4 Line Outs
5. SPDIFOut Encoded Digital Audio (Surround Sound) requires DD/DTS source, DD/DTS player (Plex, XBMC, Boxee) and DD/DTS sound system. Audi MIDI Setup/Audio Devices/Digital Output/ always shows 2 Channel Stereo. VLC encoded digital audio requires optional Optical Surround/AppleHDA binary, included in download.
