Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I've configured my soundcard properly: all sound settings are ok;
the only thing that's not working correctly it's the sound for the microphone: the volume (even if at 100% in alsamixer) is very low (I cannot use Skype or other VoIP software). Any suggestion?
If $alsamixer is set up properly and saved with $"alsactl store" to make the settings permanent( a more manual way that I configure it on a slackware system), then it might be something related to the desktop environment your using, i.e. KDE or Gnome or what-have-you.
It might not be THE solution, but its all I can think of off the top of my head.
I suspect that the existence of this option depends on your hardware, and perhaps even the name.
Be aware that some mixer apps (the gnome mixer is one of these) only show the basic controls. In the case of the gnome-volume-control program there are preferences you can set to show other controls, including in the switches tab.
Another option is using the alsamixergui tool. You may need to extend the window horizonally to see all the controls, or scroll accross to see the setting in question: Mic Boost (+20 db). You can see it highlighed in this screenshot.
Have a read of all the control names - there may be another name for similar functionality for your device.
thankyou very much, I'll try and see what It will came out
well, it seems that is not my ALSA version (I have a newer one) and I don't think I'm able to do that, It seems I have to modify the configuration file and compile ALSA again... I'm not sure I'm able to do that...
