The installation of the new policy has a lot to do with it. Firstly, check the
policy (/etc/selinux/targeted/policy) and booleans (/etc/selinux/targeted) to
make sure that selinux uses the new version of the files which is still
incorrectly marked with the .rpmnew extension.

Next, to ensure that gstreamer sees your audio/video hardware and software
(codecs, etc) you'll have to execute the command "gst-register" to make sure
that everything is _registered_ and you should get volume control back. Note: I
had to run a gstreamer app (rhythmbox) before the applet on the panel would
operate properly again.
