Internal microphone not working

Hi. Sorry for creating yet-another microphone related topic, but I've already tried some of solutions from previous topics, and no one worked for me.
The problem is that I've sound, but microphone don't record, even in arecord. I've unmuted all the channels. I've installed the pulseaudio, but it
didn't changed situation(Instead it raised problems when I plug headphones - it should mute only internal speaker, as it was happening on clean alsa, so
I uninstalled the pulseaudio to avoid annoying unmuting the chanels). When I playback what I've just recorded using arecord , I can't hear my voice, but when I hit the table with my finger near mic, I can hear that sound. I have Asus K50ij laptop and I'm sure that mic isn't broken(works on windows). Information about my system:

I'll be grateful for any help

Re: Internal microphone not working

Look carefully at your alsa info script output. Find the section labelled "AMixer Output". Notice that your mics are turned OFF and their levels are at 0%. You need to go into "alsamixer", enable all controls with the Tab key, and find the mic outputs and enable them by unmuting them ("m") key and increasing their levels.

Ok, I changed the settings in alsamixer. Now AMixer Output look like this:

But mic still not work. The only difference is the level of noise, but I know that's probably caused by microphone boost. Maybe I done it wrong? Any other ideas?
