Hi,

on Lenovo T400 laptop there's internal mic (works on other OS).

Unfortunatelly I'm stupid or it doesn't work :/

I tried:

* aucat -o /tmp/file.wav
* aucat -C0:1 -o /tmp/file.wav
* aucat -C2:3 -o /tmp/file.wav
* audacity record

(not really sure why '-CX:X'...)

It produces just same noise all the time...

I'm confused, I read FAQ but I don't have any record.source or
input.mic.source.

this is one of those stupid codecs that has hardwired connections
between ADCs and the mics.  Lenovo and Dell use these.  stupid
vendors.

you can do this:

$ aucat -l -s default -c 0:1 -C 0:1 -s internal -c 2:3 -C 2:3

that gives you two sub-devices, "default", and "internal".  you
can then specify which device to use with the AUDIODEVICE environment
variable.  "default" is the default device if not specified.  so,

$ aucat -o junk.wav
$ aucat -i junk.wav

will record from the external mic (record.adc-0:1_source=mic)
and play it on the headphones (outputs.hp_source=dac-0:1), while

$ AUDIODEVICE=internal aucat -o junk.wav
$ AUDIODEVICE=internal aucat -i junk.wav

will record from the internal mic (record.adc-2:3_source=mic2) and
play it back on the speaker (outputs.spkr_source=dac-2:3).

and I know mic2 is the internal speaker because there is a 
'mic_sense' control, which means 'mic' is a jack.

I'm working on making mic switching automatic when a mic jack is
plugged/unplugged, but there are still some issues to be worked out.
