Bug Description
Built-mic always capture sounds automatically about 20s later when the other audio stopped,
And the sound from the built-mic would be turuned off if you start an audio configure tool OR just play an audio file.
It's very strange that I have already set the MIC playback to MUTE in alsamixer.
It happened even pulseaudio was mute.
It only happens on my built-mic , while the extra mic NOT.
I also tried to add some other opptitions in alsa-base.conf, for example model=laptop,
this phenomenon will disappear ,BUT in that case ,my built-in mic would never work!
