Update 6/25/2012 -
10.7.4 AppleHDA.kext available in MultiBeast 4.6.0 and newer
Select 888_v100202 or 888_v100302
The ALC888 edited Lion AppleHDA.kext is available for Lion 10.7.2/.3 and motherboards with the Realtek ALC888 audio codec . Supports most Lion analog and digital audio capabilities. Users interested in capabilities beyond standard on board audio should consider this option for HDMi audio (discrete and HD3000 integrated), front panel audio and more. This kext supports two layout ids: layout_id 888 for full 888 analog audio on any 888 motherboard with or without discrete graphics card HDMI audio (Note 1) and layout_id 388 for 888 analog audio on a 888 Sandy Bridge motherboard with HD3000 HDMI audio (Note 2)
Verify the audio codec device_id for compatibility rather the product name (Note 4). For example, the ALC1200 is actually the ALC888
