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.
Absolutely... IMO Pulseaudio needs some serious justification for its direction.
