Why?  As I mentioned in another post, lowering hardware volume results 
in a reduction of bit-depth, and thus sound quality.  PA is free to mix 
at a higher bit-depth than the hardware supports in order to avoid this, 
but the hardware can't.

Actually my experiment with PA ended and thus I'm not using it any 
longer.  It didn't provide anything new to me that I didn't have before, 
but introduced new problems instead; there's no reason at all for me to 
use it.  I hope you'll be able to solve any remaining issues with it 
(mplayer with PA is something I simply cannot live with.)
