黑苹果HD5500核显输出HDMI音频

效果图

驱动原理

1. 注入的ID可以是16160002或者是16260006
2. 在DSDT中，B0D3需要更名为HDAU,GFX0需要更名为IGPU.
3. HDAU注入的音频ID为3，hda-gfx值为onboard-2,IGPU的hda-gfx值也为onboard-2。

SSDT注入

注意：使用SSDT时，需要禁用ACPI中的change GFX0 to IGPU以及change B0D3 to HDAU,否则可能导致系统无法进入
使用MaciASL新建一个dsl文件，复制以下代码后，编译生成aml文件，放入Clover\ACPI\patched目录下。

代码中注入的ID为16260006

使用Rehabman的config_HD5300_5500_6000.plist打补丁

因为注入的ID为16260006，所以用Clover Configurator在Clover中的KextsToPatch应用以下补丁
