I'm not really sure how this applies in the context of a Maemo, but
certainly on desktop targets it's generally not advised any more to run
a single pulseaudio daemon, but rather run one pa daemon per user
accessing sound. This allows for user switching to work properly. High
priority and real time access and such like is handled by policy kit
which is good modular design. If you were to run as a regular user then
you wouldn't need all this group stuff (console kit should ensure that
the currently active user has the right to access the audio device so
you don't need to add the user to the audio group).

Can you create the folder /tmp/pulse-user yourself? Can you chown and
chmod OK on the filesystem? Perhaps it is a FAT filesystem and pulse is
failing because the chown/chmod is not working? (not looked at the code
for a while so not 100% sure on that one).

As above but with the caveat that I'd generally recommend just running
it as your regular user unless you have good reason to do otherwise :)
