First, I like pulseaudio, especially the ability of moving streams from one 
sink to another is awesome for laptops with external sound card :o)

But imo hw mixer (or other hw parts) are not that bad... we still have hw 
accelerated graphic, math,... why not sound? Also this remains me that 
pulseaudio eats 24 % of my (1.6GHz) cpu when mapping stereo stream to 5.1 
which (I suppose) some hw mixer could do while letting cpu free for other 
tasks.
