More info, step by step: 1. I boot the computer. 2. When GDM appears, I go into VT1 (Ctrl-Alt-F1) and log into my user. 3. If I do "alsamixer -Dhw:0" or "alsamixer -c0", I get all the channels unmuted. 4. If I then do "alsamixer", I get only one muted PulseAudio channel, and the following error messages in the console: I: caps.c: Limited capabilities successfully to CAP_SYS_NICE. I: caps.c: Dropping root privileges. I: caps.c: Limited capabilities successfully to CAP_SYS_NICE. 5. Since then, If I repeat "alsamixer -Dhw:0" or "alsamixer -c0", I get the Master channel muted. 6. To unmute the Master channel previously muted on step #5, I need to do "sudo /lib/udev/alsa-utils". After that, all the channels gets unmuted and all works OK.
