Many thanks to kimsland & turbo1!!!!!!!!!!!!!
After 6 months without sound everything is now working!! Amazing!!
Here's what happened:
I made sure all my previous drivers were uninstalled in Device Manager (including Hidden ones) and Add/Remove Programs. I also ran CCleaner again and did both the cleaner and the registry tool cleaner. I shut everything down and took out the PCI sound card that I borrowed from my friendI then booted back up, leaving the onboard sound off in the BIOS for now. Everything booted up fine and it didn't ask for any drivers or anything (as it shouldn't because there was no PCI card and the sound was still off in the BIOS). I double-checked and all the drivers and everything were still gone. So I rebooted and turned the onboard chip on in the BIOS.
Now here is where it gets a bit interesting. After turning the onboard chip on in the BIOS Windows wouldn't load. It came up to the Windows XP loading screen and just hung with the blue bar going across the bottom indefinitely. I let it sit over 10 minutes but it just hang with the blue bar moving. So I manually reset (had no choice) and then it gave me the prompt about how "Windows didn't start correctly last time..." and I chose "Use last known good configuration." Still didn't work. It still hang just like before. So I manually reset again and this time chose "Safe Mode with Networking." It booted up fine in Safe Mode.
So then I was in safe mode and I went into device manager and noticed that I actually a "CMI8738/C3Dx PCI Audio Device" entry under Sound, Video and game controllers. That was cause for excitement since I haven't seen that entry in months.
But I still didn't have sound. So I first tried the newest drivers from SOYO's site that I had tried before and that kimsland posted above in #. To my disappointment I immediately received the notorious
"Our audio chip provides mult-speaker surround and realistic sound effects. Due to the fact that your computer is not equipped with our audio chip, you can not avail yourself of these advanced features. For more information, please contact your computer dealer - C-Media Electronic Inc. - Website http://www.cmedia.com.tw"
So, I then tried the older drivers which I tried before and which kimsland had posted above in # and said to try if the new ones didn't work. Well, they worked! During the installation I received two balloons at the bottom right that said "Found Multimedia Audio Controller" and "Found CMI8738/C3Dx PCI Audio Device." After a few seconds I got a prompt that said they were installed SUCCESSFULLY

and that I needed to reboot for it to take effect. After a few more seconds the driver install that was still running also gave me the option to reboot if I wanted the drivers to work properly. So I rebooted.
Now I was still in safe mode when all that was going on but when I rebooted I loaded Windows regularly and behold! not only did it windows not hang on startup this time, but I also had sound!! Nice indeed. At that point I also received a prompt to pick 2, 4, 5 speaker setup from C-media which I did and that worked fine.
So, I now have sound (did I mention I'm extremely excited about that yet?) and I am now showing this in my device manager
View attachment 28602 which, if you compare from an earlier posting, is much better! Also, Everest now finds my sound info just fine and I've enclosed a posting of that as well.

I also actually have the driver listed in my Add/Remove Programs which wasn't there before either so it really does look like the install was an all around success.
Now I haven't reinstalled the PCI Audio Applications software yet, but I'm going to try that next. I set a system restore point in case something crazy happens, but at this point I'm hoping for the best.
Let me just thank you both again for your patience and continual posting over the last month. I appreciate it so much and I've learned a ton from the process!! I've tried to show the solution as best I could in this post, but if either one of you think that there is more info that I could post that would benefit others, please let me know and I will post it. I truly hope that this thread will help others with similar problems!!
I'll post back after I try to install the PCI Audio Applications...which probably won't be until tomorrow.
Many, MANY thanks again!!
