10.11.4 will break audio for those using AppleHDA injectors with symlink to AppleHDA binary (as in so-called "dummyHDA kexts).
10.11.4版本会使之前那些注入的声卡驱动全部失效（比如命名为 dummyhda.kext)
You need to fix the Info.plist in your AppleHDA injector kext. 你需要修改注入声卡驱动下的info.plist 文件
In 10.11.4 new requirements for OSBundleLibraries:
com.apple.iokit.IOACPIFamily 1.2.0a1
com.apple.iokit.IOPCIFamily 1.1
10.11.4 info.plist 文件里OSBundleLibraries 下增加了下面两个条目
If you look at the Info.plist for AppleHDA.kext in 10.11.4, you will see the new entries.
(compare with 10.11.3)
你可以看看10.11.4的AppleHDA.kext 下的info.plist 文件 在对比10.11.3 ，你会看到这些更新的条目。
Copy your AppleHDA injector kext to a temporary place (such as the desktop), make the edits to the Info.plist, re-install with a kext installer.
复制你的注入声卡驱动到一个临时的地方比如桌面 用plistedit编辑info.plist 保存并用安装器安装
And don't forget about the cache rebuild requirements when using AppleHDA injectors.
并且别忘记针对刚才安装的驱动进行缓存清理和权限修复。
测试有效，顶帖！
