The hardware is an integrated HDA Intel audio sound card.  The 
/proc/asound/pcm file has this listed:

00-00: STAC92xx Analog : STAC92xx Analog : playback 1 : capture 2
00-01: STAC92xx Digital : STAC92xx Digital : playback 1
00-03: INTEL HDMI 0 : INTEL HDMI 0 : playback 1

Yes, this audio works just fine within Kubuntu.  Here is the output from 
the 'lsmod' binary:

Seems to be getting the drivers loaded correctly, I just have no idea 
why it's not playing.  Also, if I'm missing information to help with a 
question, please don't just ignore it, but ask me for whatever 
information you need to help resolve the problem.  Sometimes I forget to 
include certain information or don't know what to post so any of the 
people here can help fix the issue. :)  You guys have waaaaaay more 
knowledge about this than I do after all. :)

Thanks,
Dave
