I got the Update and it worked just fine. The files were updated to
the following:
[karl@localhost ~]$ rpm -q gstreamer
gstreamer-0.10.11-1.fc6
[karl@localhost ~]$ rpm -q gstreamer-plugins-good
gstreamer-plugins-good-0.10.4-3.fc6
[karl@localhost ~]$ rpm -q gstreamer-plugins-base
gstreamer-plugins-base-0.10.11-1.fc6
[karl@localhost ~]$ rpm -q gstreamer-tools
gstreamer-tools-0.10.11-1.fc6
[karl@localhost ~]$
These rpm packages support the bad Volume Control with only a
single tab. Looks like you need to go clear back to the original FC6 files.
