Ah! OK, I'll see if I can help from that point.

I am assuming that you have the setting from earlier still intact
(System->Preferences->Hardware->Multimedia->audio->Default output
plugin=ESD) Note: the path may be a tad different depending on the Gnome
version (it changes EVERY release!). That will set the the default audio
output device to be ESD for the entire gnome environment.

Now you need to install mplayer and mplayerplug-in and the codecs
packages so you can play every multimedia format on the web. Easy way:
get the yum repo set up for livna (go here:
http://rpm.livna.org/rlowiki/ and get the rpm for the repo based on your
distro - K12LTSP5 is out of support, K12LTSP6 is Fedora 6 which also
works well for K12LTSP5-EL). Once that repo rpm is installed just run
"yum install mplayer mplayergui mplayerplug-in" and it will install the
needed parts. 

But the codecs package is still a manual install. Don't worry, it's
easy. Get it from:

This pile of files needs to exist inside /usr/lib/codecs  (which is
installed by mplayer). Untar it with "cd /usr/lib/codecs  && tar xvjf
<path to file>" Now "mv essential/* ." and rmdir essential

A confession: My Fedora7 machine can play everything but I _don't_ seem
to have the essential codecs installed. I suspect that they are
statically compiled into the mplayer but I have not checked.

Now log out and back in once to reset your environment and start
firefox. Put "about:plugins" into the URL bar and you should now have
the ability to play oodles of web video junk.

You still need Adobe Flash and their site will let you install an Adobe
repo file so you can easily keep flashplayer up to date.
