That happens, because default.pa needs to contain something - I
remember correctly, pulseaudio checks if there are any modules loaded,
and if not, it refuses to start. Anyway, default.pa should load at
least the communication protoco module and modules for output devices.
So, the correct procedure is to copy /etc/pulse/default.pa to
~/.pulse/ and then do the edits in the personal copy.

If you give just two commas as the control argument, the module
refuses to load, because it requires 15 parameters, whereas the two
commas translate to just three parameters (with default values). Most
of the error messages went to syslog, since you started pulseaudio
with the -D switch (D as in daemonize). Leave -D out and you get all
output to the console.

I hope so too :)
