Sorry to reply to myself, but I need to find out more
before I put the blame on one program.  I did the
following:  


I run pulseaudio from command line, I get 

[olivares localhost ~]$ pulseaudio
[WARN  2782]
polkit-session.c:144:polkit_session_set_uid(): session
!= NULL
 Not built with -rdynamic so unable to print a
backtrace
E: polkit.c: Cannot set UID on session object.
N: main.c: Called SUID root and
real-time/high-priority scheduling was requested in
the configuration. However, we lack the necessary
priviliges:
N: main.c: We are not in group 'pulse-rt' and
PolicyKit refuse to grant us priviliges. Dropping SUID
again.
N: main.c: For enabling real-time scheduling please
acquire the appropriate PolicyKit priviliges, or
become a member of 'pulse-rt', or increase the
RLIMIT_NICE/RLIMIT_RTPRIO resource limits for this
user.
E: pid.c: Daemon already running.
E: main.c: pa_pid_file_create() failed.
process 2782: dbus_shutdown() called but connections
were still live. This probably means the application
did not drop all its references to bus connections.
  D-Bus not built with -rdynamic so unable to print a
backtrace
Aborted
[olivares localhost ~]$ 

So it could be a number of things.  

Then, I also get selinux setroubleshoot message again:


Summary:

SELinux is preventing
dbus-daemon-lau(/lib/dbus-1/dbus-daemon-launch-helper)
(system_dbusd_t) "execute" to <Unknown>
(consolekit_exec_t).

Detailed Description:

SELinux denied access requested by
dbus-daemon-lau(/lib/dbus-1/dbus-daemon-launch-helper).
It is not expected that
this access is required by
dbus-daemon-lau(/lib/dbus-1/dbus-daemon-launch-helper)
and this access may
signal an intrusion attempt. It is also possible that
the specific version or
configuration of the application is causing it to
require additional access.

Allowing Access:

Sometimes labeling problems can cause SELinux denials.
You could try to restore
the default system file context for <Unknown>,

restorecon -v <Unknown>

If this does not work, there is currently no automatic
way to allow this access.
Instead, you can generate a local policy module to
allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385)
Or you can disable
SELinux protection altogether. Disabling SELinux
protection is not recommended.
Please file a bug report
(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.
