It's a pretty stupid question to ask why you are stupid :)

I don't think it's alsa-lib that prevents the negative or non-zero
integer range.  The fact amixer works implies that it's an
app-specific bug.  But I'm not 100% sure and need more
inside-looking.

Right now, the range 0-max would make your life easier, I guess.

The min value is an API definition, and implemented and worked once.
But no drivers used yet.  So, there might be a breakage.  It's of
course to be fixed.
