I guess mpd should transition to pulseaudio? Miroslav have we tried this in the past? AFAIK yes and it caused issues. We could try to re-test it. Basically the idea is we have pulseaudio running in the caller domain. gpg.te: pulseaudio_exec(gpg_pinentry_t) mozilla.te: pulseaudio_exec(mozilla_t) mozilla.te: pulseaudio_exec(mozilla_plugin_t) mpd.te: pulseaudio_exec(mpd_t) nsplugin.te: pulseaudio_exec(nsplugin_t) Ok then lets add the access. selinux-policy-3.12.1-74.3.fc19 has been submitted as an update for Fedora 19. https://admin.fedoraproject.org/updates/selinux-policy-3.12.1-74.3.fc19 Package selinux-policy-3.12.1-74.3.fc19: * should fix your issue, * was pushed to the Fedora 19 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing selinux-policy-3.12.1-74.3.fc19' as soon as you are able to. Please go to the following url: https://admin.fedoraproject.org/updates/FEDORA-2013-16580/selinux-policy-3.12.1-74.3.fc19 then log in and leave karma (feedback). selinux-policy-3.12.1-74.3.fc19 has been pushed to the Fedora 19 stable repository. If problems still persist, please make note of it in this bug report. This still happens on Fedora 20:
SELinux is preventing /usr/bin/pulseaudio from using the setcap access on a process.
***** Plugin mozplugger (99.1 confidence) suggests ************************
If you want to use the plugin package
Then you must turn off SELinux controls on the Firefox plugins.
Do
# setsebool -P unconfined_mozilla_plugin_transition 0
***** Plugin catchall (1.81 confidence) suggests **************************
If you believe that pulseaudio should be allowed setcap access on processes labeled mozilla_plugin_t by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep pulseaudio /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Somehow, removing ~/.config/pulse/ seems to have fixed the problem.
