Bug#793170: pulseaudio: Audio system hangs (120s timeout) while waiting for pulseaudio connection

Package: pulseaudio
Version: 6.0-2
Severity: normal
Dear Maintainer,
After a system upgrade ~2 weeks ago, my audio system started to hang, and I can
no longer play any audio files or videos. I'm also unable to reboot or
shutdown, because the system hangs indefinitely waiting for the pulseaudio
process to terminate (although SysRq+B still works).
Things I have tried (without success):
* Restarting/killing pulseaudio server (can't be killed)
* Changing kernels
* Removing alsa
* Changing to system-wide pulseaudio
* Adding 'tsched=0' to udev/hal-detect lines in default.pa/system.pa
* Switching window managers (KDE -> new KDE / plasma, MATE)
I would like to be able to play audio, as it is useful for video conferencing
on this computer.
Here are some kernel lines that may be useful (notice the 120s gap between
successive messages):

# Start the PulseAudio sound server in system mode.
# (enables the pulseaudio init script - requires that users be in the
# pulse-access group)
# System mode is not the recommended way to run PulseAudio as it has some
# limitations (such as no shared memory access) and could potentially allow
# users to disconnect or redirect each others' audio streams. The
# recommended way to run PulseAudio is as a per-session daemon. For GNOME/KDE/
# Xfce sessions in Ubuntu Lucid/10.04, /etc/xdg/autostart/pulseaudio.desktop
# handles this function of automatically starting PulseAudio on login, and for
# it to work correctly your user must *not* have "autospawn = no" set in
# ~/.pulse/client.conf (or in /etc/pulse/client.conf). By default, autospawn
# is enabled. For other sessions, you can simply start PulseAudio with
# "pulseaudio --daemonize".
# 0 = don't start in system mode, 1 = start in system mode
PULSEAUDIO_SYSTEM_START=0
# Prevent users from dynamically loading modules into the PulseAudio sound
# server. Dynamic module loading enhances the flexibility of the PulseAudio
# system, but may pose a security risk.
# 0 = no, 1 = yes
