Hi,
I have 2 microphones on my laptop: 1 pluggable on the mic port and 1 on the surface . Is there any way to receive events/signal that the microphone on the mic port is connected/disconnected.
I want to implement this feature in a recording program.
Thank you

If supported by the hardware and the driver, such jack connection events are reported through an input device (/dev/input/*). The input device interface is somewhat documented at the end of linux/Documentation/input/input.txt.
