>From what I learnt from Hui Wang, it is not easy to backport these 3 commits to 16.04, or even it is not possible at all. These commits make a great change for pulseaudio core as well as some other modules, it will affect a lot of existing functions in the pulesaudio. The 1st commit looks like below. I will leave the decision to desktop team if we want to fix this in 16.04 or not.
