Yes. We set "flat-volumes = no" in /etc/pulse/daemon.conf.

Anyway. pa_simple_set_volume is a new function we added in PA simple.c.
Its just call pa_context_set_sink_input_volume to set volume value of
sink-input belongs to this new simple.

The reproduce steps is:
1.Create a new sink-input. (pa_simple_new)
2.Set the volume value of this sink-input. (pa_context_set_sink_input_volume)
3.Move this sink-input to other sink. (pa_sink_input_move_to)
Conditions:
1.No PA_SINK_SHARE_VOLUME_WITH_MASTER flags for sinks
2.flat-volumes = no
