    Note that the eight PCM channels of a K054539 do not have separate
    volume controls. Considering the global attenuation equation may not
    be entirely accurate, k054539_set_gain() provides means to control
    channel gain. It can be called anywhere but preferrably from
    DRIVER_INIT().

    Parameters:
        chip    : 0 / 1
        channel : 0 - 7
        gain    : 0.0=silent, 1.0=no gain, 2.0=twice as loud, etc.
