"volume sharing" feature patch
http://cgit.freedesktop.org/pulseaudio/pulseaudio/commit/src/pulsecore/sink-input.c?id=c9c88fb8dcbd35774e7aaae09e057e1b8bcdc3d4 

When a sink-input has been moved to a new proper sink, for the regular stream
case(flat disabled), we have to update sink-inputs' volume as
"i->reference_ratio".

In my case, I just create a new sink-input without passing volume parameter. So
the reference_ratio is Max. Right?
And after the sink-input created finished, I changed its volume by
pa_sink_input_set_volume.
The client scenario is like below:
1.pa_simple_new
2.pa_simple_set_volume.

So, when I move this sink-input to a proper sink I wanted, the volume of this
sink-input always turn to Max. Cause the "i->reference_ratio" is Max.

Anyway, I don't understand why we have to update the sink-input volume as
"i->reference_ratio" in the regular stream case.

If you have any idea, please share with us.

Looking forward to your reply.
