All the volumes on on card:0 (HDA Intel - Analog Devices AD1981) are set
to 100%, and they don't move when I press the grey "volume up" and "volume
down" buttons.
It seems the audio feeds into this internal mixer. To explain it via some
ascii diagram:

    HDA Intel --> ThinkPad Console Audio Control --> Speakers
       ^               ^

       |               +-- I am not able to control this via command line
       +---------------- I can control this via command line

When I set master volume on card:0 to 100% the audio gets louder, but you
can squeeze a good 50% more via the grey buttons.
