I login to the desktop using GDM.

To me Fedora 10 appears to set the permissions of the ALSA sound
devices to read-write for root only and none for all other users.  To
allow this to work pulseaudio is a setuid root executable.

However my workaround on my broken work desktop was to allow all users
read-write access to the sound devices, so now pulseaudio can access
the sound device but it still fails to start.
