推荐答案

AFAIK，您不能没有一些专门的硬件来监视物理端口.

AFAIK, you can''t, not without some specialized hardware to monitor the physical port.

特定于驱动程序的监视，如果完全支持的话.并非所有的声卡都支持报告插孔状态.

也没有标准接口可以检查或获取通知.您必须编写特定于音频驱动程序的代码才能获取任何类型的通知，并且仅当音频驱动程序公开了这样做的接口时.

Monitoring that is driver specific, if it''s supported at all. Not all audio cards support reporting jack status.

There is also no standard interface to check for that or get notifications for it. You''d have to write code specific to the audio driver to get any kind of notification and that''s only if the audio driver exposes an interface to do so.
