Update 6/25/2012 -
10.7.4 AppleHDA.kext available in MultiBeast 4.6.0 and newer
Select 887_v100202 or 887_v100302
The ALC887 edited Lion AppleHDA.kext is available for Lion 10.7.2/.3 and motherboards with the Realtek ALC887 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 three Audio IDs: Audio ID: 887 for full 887 analog audio on any 887 motherboard with or without discrete graphics card HDMI audio (Note 1), lAudio ID: 387 for 887 analog audio on a 887 Sandy Bridge motherboard with HD3000 HDMI audio (Note 2) and Audio ID 287 for 3 port 887 analog audio on any 887 motherboard with or without discrete graphics card HDMI audio (Note 1).
Verify the audio codec device_id for compatibility rather the product name (Note 4). For example, the ALC888B and ALC888S are actually the ALC887
