It's interesting that when I plug in a headphone or an external
microphone, the build in headphone and microphone will not work.
Is it a driver feature or the hardware do it?
Can anyone give some clue? I'd like to see the code but don't know how
to start. Please give me help. Thx!

Needs more hardware information of your device for better diagnosis.
I guess it's a hardware, but some hda-intel drivers do that by
themselves for usability, for example.

I have test on my laptop by playing a long .wav file.
During playing, I plugged the external headphone, and the sound is
continuously and switch from external headphone to internal speaker.
It uses hda-intel driver. Does this mean it's the hardware do it?
Thx
