If there's nothing in syslog, but Pulseaudio is definitely crashing, then it's
probably a segfault. For debugging that, do the following in a terminal:

echo autospawn = no >> ~/.pulse/client.conf
killall pulseaudio
LANG=C LD_BIND_NOW=1 gdb pulseaudio

At the gdb prompt, enter
run -vvv --log-time

When the crash happens, enter these commands and save the output:
thread apply all bt
thread apply all bt full

The first command prints the backtrace in a more readable format, and the
second command prints the backtrace with more information.

The log output before the crash is useful too.
