Rodnay has appropriate permissions, and the group is "root", so this won't
help.

Note that the error was:
  device /dev/dsp can't be opened (no such device)

This isn't a permissions problem, but rather a driver issue.  From the
looks of it, the sound card module is not loaded, and it's not compiled
into the kernel either.

Rodney, try looking at your module listing with "lsmod".  You should find
that you don't have any sound driver loaded.  :-)

If you don't have it compiled, you'll need to compile it.  I've no idea
what kind of chip is in a Creative 128, but you can get an idea with
"lspci".  My sound card setting shows up as:

00:10.0 Multimedia audio controller: Ensoniq ES1371 [AudioPCI-97] (rev 08)

So I compiled the es1371.o module.

Now I can't remember the Redhat way of automatically loading the correct
module when you open /dev/dsp (device 14,3 as you can see in your listing
above).  As a hint, on Debian you add an entry to the
/etc/modutils/arch/i386 file as:

alias sound-slot-0 es1371

Or even:

alias char-major-14-3 es1371

This ends up getting copied to a file called /etc/modules.conf (it used to
be /etc/conf.modules, but I don't know what Redhat is using at the moment)

Anyway, with this entry in the appropriate file, once the device numbered
14,3 gets opened, then the kernel knows which module to load for you.

The Redhat experts here can give you the details on your particular
configuration, but this should get you looking in the right place anyway.
