/** @file Sound server definitions.

    This class manages host audio HW. It's directly connected
    to a sound abstraction API (libsoundio in our case).

    Sound server provides a way to select between various
    host input and output devices independendly of emulated
    sound HW.

    Emulated sound HW only need to process sound streams.
