Yhteenveto: SELinux is preventing the /usr/bin/pulseaudio from using potentially mislabeled files (autospawn.lock). Yksityiskohtainen kuvaus: SELinux has denied pulseaudio access to potentially mislabeled file(s) (autospawn.lock). This means that SELinux will not allow pulseaudio to use these files. It is common for users to edit files in their home directory or tmp directories and then move (mv) them to system directories. The problem is that the files end up with the wrong file context which confined applications are not allowed to access. Sallitaan pääsy: If you want pulseaudio to access this files, you need to relabel them using restorecon -v 'autospawn.lock'. You might want to relabel the entire directory using restorecon -R -v ''.

THis looks like pulseaudit is trying to create autospawn.lock in a directory previosly created by a user?
seems unlikely quickly browsing the code. I see something like k = pa_sprintf_malloc("%s/%s-runtime", get_pulse_home (), get_machine_id ()); so it doesn't seem like a dir a user would create But I don't know how this stuff works, cc'ing lennart
hmm, we create that lock file in a dir in /tmp. The name of that dir is randomly chosen, and verified to belong to us, so it should be set up properly.
So the directory is shared between all users of pulseaudio even if pulseaudio is running as root? Versus a non root UID?
