G60-458DX Windows 8 upgrade NO SOUND...have tried "everything!"

Question

Greetings,
I have an older G60-458DX notebook that I upgraded to Windows 8 64-bit.
I have lost sound from both the internal speakers and anything plugged into the headphone jack. I can see levels fluxuate on the taskbar volume control when I move the slider.
I have tried the following with no success amoung other things:
Used Windows troubleshooting feature in Windows 8
Disables and enables the drivers for sound device as well as tried to upgrade the drivers (already the most current)
Checked all sound software access points
Some of the research I read indicated that HP was not going to support older hardware with driver updates for Windows 8. Is there a workaround for this issue? Could I used a USB external soundcard and bi-pass the non-fuctioning drivers?
This is my wife's computer and while she likes Windows 8, she NEEDS SOUND. Thank you!

Brett,
You are "far and away up the soundless creek" and I offer you a paddle:
Running Drivers and Software in Compatibility Mode by AttackOfZaq
There is a hope this will work to bring sound where there is now silence.
It is possible that it may turn out to be a very small paddle in a very large creek.
Good Luck!
