F10 - pulseaudio not running

[Mike Fleetwood <mike fleetwood googlemail com>]

Hi,

On my work Fedora 10 desktop (upgraded directly from F8) pulseaudio
doesn't run and I don't know how to fix it.  On my home Fedora 10
desktop (upgraded to F9 then F10) pulseaudio runs OK.  As a workaround
I have run "chmod o+rw /dev/snd/*" to allow Audacious audio player as
non-root user access to ALSA kernel audio devices to be able to play
music.  Help troubleshooting pulseaudio appreciated.

Attempting to start pulseaudio manually ...
[mfleetwo mfleetwo3 ~]$ pulseaudio --start --log-target=syslog
I: caps.c: Limited capabilities successfully to CAP_SYS_NICE.
I: caps.c: Dropping root privileges.

Thanks in advance,
