Hi Bookworm,
I have the same problem with most of the people here,
and that is, I lost the sound after re-format my PC.
However, before I found this forum, I have tried to install Realtek and Viyln Deck Audio drivers.
When installing Realtek,when its installing midway, I was told that it hasn't been tested yet and given 2 buttons to press:
1) Continue anyway
2) STOP Installation
I clicked "continue anyway", and about 30 secs after that, my comp restart on its own, and after I checked the control panel, nothing is installed.
Then it says hardware wasn't installed properly and unable to function.
So I thought Realtek isn't compatible with my sound card, so I tried Vinyl Deck audio driver. And I also pressed the "continue anyway", but its got installed smoothly, I can play my songs again, and the volume icon appear as normal at the bottom of right hand corner, but NO SOUND at all...
Now, I have uninstalled all of them.
Oh, I didn't do what you suggested, system restoring thing...
Below is the advise from Belarc:
