Notes and Observations:

** Audio works great when you follow the directions below:

1. Download the following 4 ALSA packages from the ALSA Sound project. Get the 1.0.10+ packages. 
Older ones will not work. (the URL as of today is: http://www.alsa-project.org/ )
 
alsa-lib 
alsa-drivers
alsa-utils 
alsa-oss 

2. Unpack and install all  packages in the order alsa-lib, alsa-drivers, alsa-utils, alsa-oss. 
They are standard ./configure, make, make install type packages. 

3. Reboot to get rid of the old broken stuff that was loaded. 

4. Run alsamixer.  Umute -everything- and raise the volume to a level where you can hear it.  
It is utterly important is to unmute -master mono-, -wave-, and -master stereo- to get any sound at all.   
   (Note: I just used the RedHat sound control and it worked fine after reboot)
	 
5. Now you can play sounds back, and the X mixer should work.
