如何使用AppleALC
如果您的编解码器支持，您需要完成的唯一任务是加载内核扩展，并查看它是否工作。您可以使用您的引导加载程序(比如：Clover)，但请记住在AppleHDA之前加载AppleALC（有关更多详细信息，请参阅sudo kextstat输出）。
请注意，Lilu 也必须出现在AppleALC上。
按照一个易于使用的指南来添加您的编解码器支持，如果它不在这里。请分享您的成功结果。
备注：AppleALC不处理layout-id值，它希望你提供正确的DSDT(SSDT)。
如何控制AppleALC
AppleALC接受不同的引导参数来控制其行为：
-
-alcoff- 禁用自身; -
-alcdbg- 打印调试信息（如果扩展在调试模式下编译）; -
-alcbeta- 在不支持的系统（通常未发布或旧版）上启用AppleALC; -
-x或-s- 也将禁用AppleALC。 - 所有Lilu启动参数都会影响AppleALC。
如何提取调试日志
在使用-alcdbg -liludbg引导后，在终端Terminal中运行以下命令并保存输出。
10.12及以后版本：
log show --predicate 'process == "kernel" AND (eventMessage CONTAINS "AppleALC" OR eventMessage CONTAINS "Lilu")' --style syslog --source
10.11及以前版本
cat /var/log/system.log | egrep '(AppleALC|Lilu)'
