Summary: SELinux is preventing /usr/bin/pulseaudio "signull" access . Detailed Description: [SELinux is in permissive mode. This access was not denied.] 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://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug report.

Which process is running as initrc_t? Music Player Daemon (MPD)? # ps -eZ | grep initrc
yes, Music Player Daemon. Not from Fedora, but from rpmfusion. /etc/init.d/mpd i updated to FC12 from FC11 last night and i wanted to test if the bug reporting is actually working now after going nowhere with hundreds of bug reports. Had i known bug reporting was actually working, i would have looked at this further on my own before reporting. There were more than 30 SELINUX errors related to mpd. i reported a handful and now Dan Walsh is involved - wow. There were official windows mpd clients infested with malware a few months back and haven't tried them again, but it made me suspicious of the mpd project.
It is probably best if we write a policy for mpd. Do you know if this is intended to be moved into Fedora?
i found mpd packages in rpmfusion and atrpm.net. i believe there are some media player clients in Fedora already. i didn't find any package review requests.
libmpd libmpdclient qmpdclient I believe we will eventually see the MPD in the repos ?
gmpc - Gnome Media Player Client
Miroslav for now lets add optional_policy(` pulseaudio_stream_connect(initrc_t) ') Since we do not know if other services will need this access.
