[pulseaudio-discuss] Issues with pulseaudio and gdm

I've posted this in the Fedora list and googled around without
success, so this is my next stop.
Long story short, I have Fedora 16, upgraded from F14 (and earlier),
but pulseaudio is not running (or dying) for the gdm+gnome-shell
session, although it *really* wants it. All normal users are fine.
The side effect is that, some while after logging in, or possibly as
I switch users, I get an entry in /var/log/messages every few seconds
about a pulseaudio authorisation error. I believe I have tracked these
down to gdm's gnome-shell & gnome-settings-daemon trying to talk to *my*
login's pulseaudio (as it's the first login and is sitting on the
Unlike my freshly-installed laptop, and the VM I created to test it,
I don't seem to have one run from start-up, although it might be
stopping before or as I log in.
I've tried running pulseaudio manually as gdm, but it seems to just
exit by its own volition. I'm running strace again on a daemon I've run
up now. I tried earlier today from my laptop but couldn't see anything
but a seeming deliberate clean exit. It doesn't automatically respawn
like I'd expect.
I've even copied the X11-start-pulseaudio .desktop file into gdm's
autostart directory, and this seems to (usually) work from power up (I
actually get an audio icon in gdm's gnome-shell's panel that makes a
sound) but it goes when gdm's pulseaudio does, which I *think* is when I
first log in.
Has anyone got any ideas as to where I should start looking at this?
What's *supposed* to start pulseaudio? I replaced pulseaudio in my
test VM with a script that would do a ps and then run the real
pulseaudio, and that indicates that it's gnome-settings-daemon that's
spawning the pa exe, but I can't find anything explicit in the gsd source.
I'm running the rtkit daemon, I have gdm in the pulse-rt and
pulse-access groups (along with all local users), and I *don't* have
anyone in the audio group (which I think causes lock problems).
I am having random rhythmbox lock-up issues which may or may not be
related, and I *used* to have a problem with gdm locking pulseaudio out
(such the my user account could often not access sound), so I tried a
couple of fixes at the time to stop gdm trying to make sounds. I
*think* I've undone these, but may have something stray hanging about.
I can't see anything in files, gconf or dconf, though.
All ideas gratefully received, this is driving me potty!
