Bug#674935: pulseaudio: Disable flat volumes

[Gabriel Corona]

I agree with this, flat-volumes = yes [0]
is *very* dangerous.

As reported in many oher places, it can cause
hearing damage [1,2,3] as there is no reliable
way to limit the master volume : any appliaction
might start and decide to use it's

With "flat-volume = yes", I need to set the sound
of each application to something like 15% in
order to have a reasonable volume. If any
application decides to set its volume to anything
higher than 30%, the volume is unbearable.
