Acer 5750g的笔记本，安装的是Lion 10.7.3，驱动具体见：https://bbs.pcbeta.com/viewthread-970879-1-1.html
刚开始使用的VoodooHDA驱动的声卡，后来发现开机启动偶尔会五国，所以尝试修改AppleHDA，由于没有相关知识和经验，就只能在别人的基础上依葫芦画瓢，主要借鉴jingehongyan的帖子：https://bbs.pcbeta.com/viewthread-1006317-1-1.html
我的声卡的信息如下：
Address: 0 Vendor Id: 0x10ec0269 0x12 0x411111f0 [N/A] Speaker at Ext Rear Black 0x14 0x99130110 [Fixed] Speaker at Int ATAPI UnKnown 0x17 0x411111f0 [N/A] Speaker at Ext Rear Black 0x18 0x03a19820 [Jack] Mic at Ext Left Pink 0x19 0x411111f0 [N/A] Speaker at Ext Rear Black 0x1a 0x411111f0 [N/A] Speaker at Ext Rear Black 0x1b 0x99a30930 [Fixed] Mic at Int ATAPI Unknown 0x1d 0x598301f0 [N/A] Line In at Int ATAPI Unknown 0x1e 0x411111f0 [N/A] Speaker at Ext Rear Black 0x21 0x0321101f [Jack] HP Out at Ext Left Black
有用接口的PathMaps如下： 0x14 IntSpeaker 2，12，20 (3，13，20) 0x21 Headphone 2，12，33 (3，13，33) 0x18 LineIn 24，35，8 (24，34，9) 0x1b Mic 27，35，8 (27，34，9)
结合jingehongyan的帖子和自己在win7下面获得的ConfigData，尝试得到ConfigData如下：
01471C10 01471D01 01471E13 01471F99 01871C20 01871D10 01871E81 01871F03 01B71C30 01B71D09 01B71EA3 01B71F99 02171C1F 02171D10 02171E21 02171F03 01470C02
最后修改jingehongyan帖子中自动切换的AppleHDA.kext即可，内置喇叭、内置麦克风、耳机均正常，且能自动切换。
DSDT的修改如下：

}, Local0)

Return (Local0)
}
}

UseKernelCache设置为Yes后喇叭灰色无声音的问题，解决办法见7F。 |
