~ ALC 888 and ALC 1200 with VoodooHDA ~

VoodooHDA 有時會同nvidia 等display card 的hdmi audio out 撞左

VoodooHDA 會以為display card 個張先係main audio card

以下方法可以解決問題

[1]先確定graphic card 安裝成功，無有問題

到system report.. Hardware>graphics/Displays check 一下graphic card 的vendeor id and device id

先到 /system/library/extensions 找VoodooHDA.kext

右click show package content 入到去folder 改以下 file ./contents/Info.plist

找

<key>IOMatchCategory</key>
<string>VoodooHDADevice</string>

在這code 下加入vendeor id and device id for skipping

<key>VoodooHDAVidSkip</key>
<string>0x10de</string>
<key>VoodooHDADivSkip</key>
<string>0x1244</string>

之後clear caches

sudo -i
cd /system/library/Caches 
rm -r com.apple.kext.caches
