Hi Robert,
I'm copying couple of our Tizen IVI PulseAudio experts to provide you
more insight on your question. Also general view on current situation
inline.

Hi,
I recognised that Tizen uses its own PulseAudio version, e.g.
pa_sink_input_set_volume_ramp in pulsecore is something Tizen specific.
Could someone please let me know about the current status of integrating
changes on PulseAudio back to upstream project?
What we currently have in Tizen is heavily patched PA 4.0 to enable
BlueZ 5 support (A2DP+HFP), more advanced ivi specific routing
functionality in its own module (pulseaudio-module-murphy-ivi) and a
bunch of Tizen specific patches (like volume ramp you mentioned).
Our goal is to keep the delta between upstream and Tizen PulseAudio as
small as possible and contribute back to upstream what we see makes
sense. Example given quite a lot of discussion has taken place in
upstream related to routing module we are using in Tizen IVI. Sometimes
it just takes a bit longer to reach consensus on these things. We have
pushed other patches we have done in downstream to upstream as well and
some of those have been accepted, some still require more discussion.
One thing we are planning to propose in near future is upgrading to
latest PA 5.0 in Tizen. This will allow us to drop many of BlueZ 5
support patches (A2DP) we currently maintain in downstream. I'm sure we
continue to have Tizen patch set on top of upstream PA in future as well
but we hope to keep it thin.
If you have questions about specific patches I'm sure Jaska and Tanu can
help you with those.
Thanks,
Matti-Pekka
