Public bug reported:
During the start-crash loop, syslog gets this block added about once per
second:
-------
Jan 22 14:47:14 vulcan rtkit-daemon[2274]: Successfully made thread 29983 of
process 29983 (n/a) owned by '104' high priority at nice level -11.
Jan 22 14:47:14 vulcan rtkit-daemon[2274]: Supervising 4 threads of 2 processes
of 2 users.

open cookie file '/var/lib/lightdm/.config/pulse/cookie': No such file or
directory
Jan 22 14:47:14 vulcan pulseaudio[29983]: [pulseaudio] authkey.c: Failed to
load authorization key '/var/lib/lightdm/.config/pulse/cookie': No such file or
directory
Jan 22 14:47:14 vulcan pulseaudio[29983]: [pulseaudio] x11wrap.c:
XOpenDisplay() failed
Jan 22 14:47:14 vulcan pulseaudio[29983]: [pulseaudio] module.c: Failed to load
module "module-x11-bell" (argument: "sample=x11-bell"): initialization failed.
Jan 22 14:47:14 vulcan pulseaudio[29983]: [pulseaudio] main.c: Module load
failed.
Jan 22 14:47:14 vulcan pulseaudio[29983]: [pulseaudio] main.c: Failed to
initialize daemon.
Jan 22 14:47:14 vulcan pulseaudio[29980]: [pulseaudio] main.c: Daemon startup
failed.
--------
Editing /etc/pulse/default.pa and commenting out this line:
load-module module-x11-bell sample=x11-bell
...then saving the file, counting to 2 and then uncommenting it again to
back out the change, allows the process to stop bouncing.
The final entry in syslog after the above steps looks like this:
-----

Note: I checked on IRC with #pulseaudio and the users that assisted me
there were of the opinion that this is a lightdm bug and not a
pulseaudio bug.
