Hello everyone.
I can't get the microphone to work properly. I've looked on every topic in the forum related with my problem, with no luck.
Symptoms are:
arecord -vv -f dat test.wav
Works just fine.
arecord -d 5 test.wav
Doesn't work. All I can hear when I play it is really, really low noise, completely saturated.
Hangouts, Skype won't work either. Cheese also records really low audio, completely saturated.
Any clues?
Thanks in advance.

Those two are not the same thing. You have to provide more details, such as if you are using pulseaudio, what you have in your asound.conf, and if you have tried to make things work by fiddling with the alsamixer settings.

I'm using pulseaudio, this is my /etc/asound.conf:
# Use PulseAudio by default
pcm.!default {
type pulse
fallback "sysdefault"
hint {
show on
description "Default ALSA Output (currently PulseAudio Sound Server)"
}
}
ctl.!default {
type pulse
fallback "sysdefault"
}
# vim:set ft=alsaconf:
I've tried every possible alsamixer setting.
I forgot to mention, if I plug headphones with microphone it works fine. The internal mic of the laptop is the one not working.

Can you post
arecord -l
