请注意，调试器输出可能包含公共 ACX 对象的组合，例如 ACXMANAGER、ACXCIRCUITFACTORY 和 ACXCIRCUIT 以及定义为不透明的内部结构。 不保证内部类型保持不变，也不保证在 ACX 的不同版本中可用，并且不得直接调用或使用。

由于 ACX 对象是 WDF 对象，因此可以使用 ！wdfkd.wdfhandle 命令显示有关 ACXMANAGER 对象的其他信息。

ACX 驱动程序演练示例

本部分提供调试 ACX 驱动程序的演练。

符号路径

使用 .symfix 和 .sympath（设置符号路径） 命令更改符号路径。 如果将本地代码用于驱动程序，则还会向该代码添加路径。 使用 .reload（重新加载模块）命令从当前路径重新加载符号。

.symfix
.sympath+ C:\Windows-driver-samples-develop\audio\Acx\Samples\AudioCodec\Driver
.reload /f

驱动程序的调试器上下文

如果要调试活动的 ACX 驱动程序，请设置断点。 这会将调试器置于 ACX 对象的上下文中，以便能够收集和显示信息。

这些示例断点设计为在启动示例 AudioCodec 驱动程序时触发。

bm AudioCodec!DriverEntry
bm AudioCodec!AcxDriverInitialize

这些示例断点设计为在发生特定操作时触发，例如引脚或线路创建。

bm AudioCodec!AcxPinCreate
bm AudioCodec!AcxCircuitCreate
bm AudioCodec!Codec_EvtBusDeviceAdd

加载驱动程序并触发相应的断点并且有效的执行上下文可用后，请使用 ！acxkd 命令显示有关任何 ACX 对象的信息。 将 ！acxobject 命令用于常规信息和特定命令，例如 ！acxcircuit 或 ！acxpin，以获取更精细的信息。

加载 acxkd dll

使用 .load （加载扩展 DLL） 命令加载acxkd.dll扩展。

.load acxkd.dll

显示有关 ACX 驱动程序的信息

若要收集有关目标驱动程序的信息，请使用 lm （List Loaded Modules） 命令查看所有已加载的驱动程序。 然后使用 Dvm 选项显示有关感兴趣的 ACX 驱动程序的信息，如下所示。
