Optimized AppleHDA for Realtek ALC 887/888b on Lion [OLD]

toleda · Feb 19, 2012

ALC887 edited Lion AppleHDA.kext

5/2/12 - An update is available for this AppleHDA.kext; see 887_Lion_AppleHDA

Important - 2/22/12 - A problem has been identified with the 887Beta_Lion_AppleHDA_v2.1.3-2. The fix is available now. Download and install 887Beta_Lion_AppleHDA_v2.1.3-4.

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 two layout ids: layout_id 887 for full 887 analog audio on any 887 motherboard with or without discrete graphics card HDMI audio (Note 1) and layout_id 387 for 887 analog audio on a 887 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 ALC888B and ALC888S are actually the ALC887

Benefits
1. 887 on board audio
2. HDMI audio, if configured
3. Front panel audio with auto mute
4. Optical Surround Sound (Note 3)
5. Improved audio quality
6. Less popping
7. Easy installation
8. Nearly native

Requirements
1. 10.7.2/.3 - 64 bit kernel
2. ALC887 audio codec/Device_id: 10ec0887 (Note 4)
3. dsdt w/HDEF/Layout-id is 0x77 0x03 0x00 0x00
Note: For HD3000 HDMI audio; dsdt w/HDEF/Layout-id is 0x83 0x01 0x00 0x00
