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.
