Thanks for the information, the fact that you have edited 
extra-hdmi.conf is important. Unfortunately, there is nothing in the log 
that stands out as a possible cause of the regression. I can only 
suggest compiling pulseaudio from git and bisecting. There is no need to 
install pulseaudio after each compilation, you can run it from the build 
tree:

killall pulseaudio ; ./src/pulseaudio

P.S. The extra-hdmi.conf file has been removed, and its content is now 
in default.conf.
