Volume changes on the Xonar D1/DX need several milliseconds and thus are
relatively slow, compared to most on-board sound cards.  However, there
are other sound cards that behave the same.

It looks as if the gnome-applet saves all mouse moves and tries to
execute the volume changes for all intermediate positions even if the
mouse has already moved to the final position.  Please file a bug with 
that mixer.
