Summary:

SELinux is preventing /usr/bin/pulseaudio "signull" access.

Detailed Description:

SELinux denied access requested by pulseaudio. It is not expected that this
access is required by pulseaudio 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:

You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug
report.
