Description David Jaša 2014-10-03 09:58:24 UTC
Description of problem:
SELinux is preventing /usr/sbin/alsactl from 'read' accesses on the lnk_file .

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that alsactl should be allowed read access on the  lnk_file 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 alsactl /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
