Your attached log ends at this message:

    D: [pulseaudio] module-always-sink.c: Autoloading null-sink as no other sinks detected.

Is that the last message that you see, and after that PulseAudio is
stuck? If so, then it should be possible to find the infinite loop by
adding extra logging to the code that follows that message. Or if you
know how to use some profiling tool, that should do the trick as well.

As a workaround you could also try removing module-always-sink from the
configuration. Maybe you don't need it.
