I was just at Dell.com for my Optiplex 755, giving Windows 10 64-bit Preview a try.
ONLY the XP driver is listed under VISTA 64-bit, I am sure causing many to end up here.
I have not actually tried just the old XP driver R228747- seems like a waste of time.
Listed under VISTA 32-bit is Analog Devices ADI 198x Integrated HD Audio, v.6.10.2.7260, A09
R164900.exe
Compatible Systems
Precision T3400 (Late 2007)

The R614900.EXE driver listed in the years old post is correct.
Its 32 or 64 bit and its for Optiplex 330,755, Precision T3400, T5400, T7400.

Hi all. Well to my dismay, I think a Windows update scuppered my sound again!. This time even repeating the previous fix or downloading and re-installing various sound drivers, I found none worked. I was at the point of getting a replacement PC when I came across this possible fix :-
.
Start>Control Panel>All Control Panel Items>System>Advanced System Settings>Device Installation Settings
At this point I had the 'No Let Me Choose' selected and I changed to 'Yes Do This Automatically' (for Drivers) and the next day when I logged on the sound was back!
