Issue resolved. This isn't a bug with pulseaudio, the issue stemmed from the FQDN not being set properly which messed up the idmapping for NFS for the home disk. Wrong user ids (nobody) = permission problems for pulseaudio.

New install. Home directory mounted over NFS. Audio icon on menu bar shows speaker icon with dashes. Clicking on icon the menu only has volume control set to zero (can't change).,Rhythmbox link and play controls, and Sound Settings link. Would expect to have speaker icon with sound graphic, more options under the menu and to be able to adjust sound settings (e.g. volume). Reason seems to be that pulseaudio fails to start. In Syslog a series of error reports a second or two apart reporting: Mar 22 09:11:44 unbuntu-desktop pulseaudio[4095]: [pulseaudio] authkey.c: Failed to open cookie file '/home/david/.config/pulse/cookie': No such file or directory Mar 22 09:11:44 unbuntu-desktop pulseaudio[4095]: [pulseaudio] authkey.c: Failed to load authorization key '/home/david/.config/pulse/cookie': No such file or directory Mar 22 09:11:44 unbuntu-desktop pulseaudio[4098]: [pulseaudio] core-util.c: Home directory not accessible: Permission denied Mar 22 09:11:44 unbuntu-desktop pulseaudio[4095]: [pulseaudio] main.c: Daemon startup failed.
