Internal mic doesn't work on Dell mini 1010.

[mikewhatever]

The internal mic doesn't work at all on cold boot. After reloading alsa, sound is recorded by with lots of static. Changing Mic Boost or Capture levels didn't help.

The 'options snd-hda-intel model=laptop-amic' seems to be a workaround. The internal mic is now detected and works, but there is still some static noise when speaking, thought not durring pauses.

I've been able to workaround the crackling noise the microphone was recording by removing pulseaudio.

 the volume control seem have large gain (0x2e - 0x11)

you have to post the pulseaudio verbose log

did the crackling occur when capture volume is over 0dB ?

post the output of alsa-info.sh

Let me know if I need to prvide any more info.

pulseaudio verbose log when you change the capture volume from min to Max by in sound preference

[Raymond (superquad-vortex2)]

open a terminal and use alsamixer -c0 to monitor the changes in the capture volume and boost while you change the capture slider in sound preference
