Effectively, some channels were off in gnome-alsa-mixer but, unfortunately, it didn't solve my problem.
I tried with many different levels combo and I figure out that the "Front" level has absolutely no effect, from 0% to 100% (but strangely mute is effectively mute !) "Master", "Line" and "Speaker" seem to control the same level (logical, if there is no working "Front", isn't it ?) Concerning "Beep", if I un-mute it, sound become even more cracking (on headphones, still nothing on speakers). And for the two boxes "IEC958" and "IEC958 Default PCM" they do nothing (even if no one is selected). So, the "Front" level might be the problem (or the symptom ?). What's next ?
