can i get some help with this THANKS for any help!!!
You shouldn't be logging in as root. Log in only as a regular user and
use su or sudo to accomplish tasks that require root-level access. It's
extremely bad *NIX practice to log in as root and such behavior should
be avoided whenever possible.

Hi Jerry;
What Doug means is that logging in as root on your computer is dangerous
security wise and opens you up to vulnerabilities. In fact if you have
SELinux turned on in enforcing mode your problem could be that SELinux
is supressing several modules while you are logged in as root. The idea
is that root is for computer maintenance only and not for day to day
usage. Technically the root user only needs to be able to access the
hard drive and all the setting files on the computer.
I am not sure why your sound does not work under root, perhaps it could
be the root user sound profile is not set correctly.
I will be honest with you, I never log in as root user on my computer.
In fact since setting myself up in sudoers I mainly use sudo for any
command that I need root privilidge on. I usually only log in "su -"
when I am having some problems with yum. One time when there were lots
of updates sudo timed out when trying to apply the updates in yum. Also
any update to selinux policies seems to work better if you log in as "su
-" instead of using sudo. Also note, when I say I am logging in as "su
-" I mean that I am logged in under my own personal user profile, open a
terminal, and do "su -" to become root user. I am not logging into
Gnome/X as root user. The only other time I have logged in as root is
when I was updating my nvidia driver after a kernel upgrade. In that
case though I was killing x, telinit 3 at terminal, installing nvidia
driver, logging out of root, logging in as user, starting x. Even in
that case though I didn't need to log in initially as root, I could have
logged in as user and did "su -" to do my nvidia update.
All the System Preference - gui config files will prompt you for root pw
when you open them, so you don't need to log in as root to change the
system preferences.
What it comes down to is that root access is really only if you need to
configure or change a file or system setting that is inaccessible as
user. You should be able to do that with "sudo" in most cases, and in
the odd case where root access is absolutely necessary "su -" takes care
of that.
