X1C 7th（X1 Carbon 2019）ALC285的内置麦克风无法工作
本帖最后由 waysgim 于 2021-2-8 17:56 编辑通过修改AppleALC.kext，实现了声卡的4喇叭输出，耳机输出，但是，内置mic无法工作，无输入电平。
通过观察linux下（ubuntu、manjaro）的codec文件，发现没有内置mic节点，继续研究中，附上ALC285的codec文件。

如果编译AppleALC时弹出这个错误：'mach/mach_types.h' file not found，头文件找不到，是因为目录下没有下载MacKernelSDK。

经过研究，发现 X1Carbon 7th刚开始时，在linux系统下，内置mic也是无法识别，无法工作的，目前已经有了解决办法，采用sof固件，详见：https://www.sysorchestra.com/setup-soundcard-and-microphone-on-lenovo-thinkpad-x1-carbon-7th-gen-with-linux-mint-19-3/根本原因是内置mic在windows下是array micphone，即麦克风阵列，不通过codec方式，直接连接PCH？对于阵列式麦克风，该如何驱动？需要继续研究。。。

目前发现 同样有 阵列式麦克风 的 Acer Swift 3 SF314-54，声卡型号 Realtek ALC256，同样无法驱动内置mic：Built-in DMIC is not working
