Looking at the code sink_input.c

void pa_sink_input_set_volume(pa_sink_input *i, const pa_cvolume
*volume, pa_bool_t save, pa_bool_t absolute) {
    /* test ramping -> return pa_sink_input_set_volume_with_ramping(i,
volume, save, absolute, 2000 * PA_USEC_PER_MSEC); */
    return pa_sink_input_set_volume_with_ramping(i, volume, save, absolute, 0);
}

So ramp code is actually being used already theres just not a way of
setting the number of seconds at the moment

Chances of code being accepted to add the option?

Cheers
