The computer act weird suddenly that, if I plug in the headphone, I can hear the sound from the headphone. But if I plug out, there is no sound from speaker and headphone.
Before the problem appear, the sound icon at the system tray has two states of volume: one for the speaker if the headphone is not plugged in; the other for the headphone if it is plugged in.
But now, the sound icon appeared is always the volume for the headphone.
How to solve this?

I just solved the problem by disable Auto Mute from alsamixer. I am not sure what has happened, but disable Auto Mute solves the problem.
