Не работает микрофон в Dell Latitude E6410

[Andrey Tataranovich <tataranovich@gmail.com>]

Доброго времени суток,

Пытаюсь записать звук на Dell Latitude E6410. Установлен Debian Wheezy.
Проигрывание звука без проблем, как на колонки, так и на наушники. А
вот записать звук пока не получилось.

lspci -nn | grep Audio 
00:1b.0 Audio device [0403]: Intel Corporation 5 Series/3400 Series
Chipset High Definition Audio [8086:3b56] (rev 05)

grep Codec /proc/asound/card*/codec*     
/proc/asound/card0/codec#0:Codec: IDT 92HD81B1C5
/proc/asound/card0/codec#1:Codec: Conexant ID 2c06
/proc/asound/card0/codec#3:Codec: Intel IbexPeak HDMI

Пробовал прописывать model=dell-s14 для snd-hda-intel, но
результат не меняется. В alsamixer в разделе запись все включено и
выставлено на максимальную громкость.

Возможно у кого-то есть такой же ноутбук и он уже решил эту проблему.

P.S. звук записываю посредством arecord -vv /tmp/test.wav
