Jukka, what is it about the broken implementation that is broken?
I may not disagree with you that it is broken.  There was a discussion
about some god-awful stateful implementation---I don't remember how that
was resolved.

We disagree that the way to fix it is with scaling.  The way to fix it
is to tell apps, "I am a volume control.  I am adjustable in the range
[0, hwmax].  I will clamp settings greater than hwmax or less than 0."
Let the apps decide whether to scale or to provide discrete settings,
but do *not* make them represent that there are more settings than there
really are, and then conceal the dismal truth from them.

(BTW, X provides descriptions of the graphics hardware capabilities to
apps that are *much* richer than the volume-control interface I describe.)
