I tried to use tips at http://bbs.archlinux.org/viewtopic.php?id=37007 (solution by @jinn), but isn't worked.
For sound output works, I need to use an "options" at modprobe.conf:

options snd-hda-intel model=3stack

without this, I can't hear any sound without headphones neutral This chip is terrible! hmm

What I can do now ?
Thanks!

Re: Microphone and hda-intel Sigmatel chip

i don't have any problem with microphone. you need to put capture to the right input smile
Hit tab to select Capture on the View line.
go on the first or second(give it a try and see what's the right input) level and hit space

Give what you have. To someone, it may be better than you dare to think.

@wonder

Thanks for tips! Now, my mic output only noises...
In my case, the first Capture is my internal mic. I tried some combinations but, isn't worked yet.

Please, see a new shot at: http://helio.hlegius.pro.br/screens/mic_error.png

ah! I'm trying record voice using 'arecord':

$ arecord -vv -fdat foo.wav

Thanks!
