Why would normal applications NEED that information?  The user adjusts the
slider until the volume is suitable.  What good does it do to him to see
how many steps the particular hardware implementation has?  Why would every
volume control application have to do the same scaling that could just as
well be done in the audio drivers?  I don't mind being able to query the
hardware capabilities, but IMO, the application interface should be made
simple for the application developers.

BTW, how does volume control work in other BSDs, linux etc?

Oh well - I should know better and shut up.
