Martin Bauer 804cb1bfaf Give musicdolphin real sound through the HifiBerry amp ...

It was set up display-only, with alsa_device "simulate", so the UI showed a
working player that made no noise - but the Pi has a HifiBerry amp and
pi_alsasetup already put the softvol_effects slot on it. Point the backend at
it, the same way musicmouse does: a softvol control feeding dmix, so the card
stays shared with squeezelite and shairport instead of being locked.

Carry musicmouse's volume clamp over with it. Below roughly 23 the softvol
attenuation leaves nothing audible, and the ceiling keeps a UI slider from
putting the amp to full. Those numbers are tuned to musicmouse's speakers and
this is a different room, so they are a starting point.
