    Something appears to be borked in the ALSA arena. There's no actual volume coming
    out of the system, and 'alsamixer' is insisting that the volume slider only goes from 0
    to 10% or so, no further. However, experimentation shows that the volume slider
    in 'xine' *does* affect the 'Amp-Out vals' lines, and alsamixer has *no* effect on
    what 'Amp-Out vals' lists.

    A diff of alsa-info.sh for the two kernels shows them being identical, so I'm only
    attaching one copy.

    It may be the weekend before I find time to do a bisection of this.
