Comment(by yelo3):

 The "unknown" reported just pointed out that when the volume is set to 0%
 alsa can't report -inf dB. He demonstrated this by quoting the audio
 chipset specification manual.

 So, if you say that my problem of having mute at 14% is caused by the fact
 that ALSA does not put -inf when the volume is 0%, this will never be
 possible (with my chipset).
 If instead the problem is different, please tell me how can I discover
 which are the wrong dB values exported by ALSA.

 I visited this wiki page http://pulseaudio.org/wiki/BadDecibel and
 executed the application:
 ./dbverify 0 Master 30 200
 I hear the sound all the times with the same amplitude, but I don't
 understand what exactly should I do. The application output should really
 be more verbose and tell the user what to do.
