Subject: [PATCH] Fix issue 2428760: Driveabout: volume of navigator through
 Bluetooth headset much too loud.

Driveabout navigation instructions are ususally played with a loud volume in order to be heard while driving.
When in call, all audio generated by the application processor is routed to the device in use by the
call, in this case the bluetooth SCO headset. For some reason, when audio at loud volume is output
by the application processor to the bluetooth headset the sound is saturated.

The fix consists in limiting the stream volumes to -18dB when playing over a bluetooth SCO device.
