(In F11, other ways to log in should work.) 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. >From my functional home desktop ...
