Description of problem:
Happened during a yum update in which alsa-utils was updated to 0:1.0.28-1.fc21.
SELinux is preventing /usr/sbin/alsactl from 'write' accesses on the directory lock.

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

If you believe that alsactl should be allowed write access on the lock directory 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
