PA is simply one layer that, if it works with your chipset, allows control of 
more than one channel.  If it doesn't work with your chipset it falls back to 
the alsa controls.  There is no way that PA is responsible for 90% of the 
things people claim - it's simply not possible.

Yes, you can disable it or remove it, if you choose, but if also would work 
without it, it will also work with it.  FWIW PA works well on a couple of 
fedora installs here, but not on this laptop.  Every day I see a notification 
that it can't work with my chipset, so sound will fall back to Default (which 
is alsa).  I have no sound problems whatsoever.  I don't know a single 
application that doesn't work as expected (though naturally I haven't tried 
every available one).
