Windows 7 64-bit Users
1. Download ‘R145149.exe’ on dells support ftp site by using this direct link here or by going to http://search.dell.com and searching for the file ‘R145149.exe’. The file should be the first listing in the search results.
The driver itself is a Windows Vista 64-bit version of the driver and is compatible with OptiPlex GX280, GX520, GX620 and SX280 as well asDell Precision WorkStation 370, 470 and 670.
2. Double-click ‘R145149.exe’ which will run the self-extractor. Once this has finished, note the extracting location and run the installer from that directory.
You will not need to do anything else for the installer to work but if you have troubles you may want to use the ‘Run As Administrator’ setting or try changing the ‘Compatibility mode’.

No sound for me after doing this. Does it work for Windows 7 ultimate?
You can try getting it from the Microsoft Update Catalog and installing via Device Manager:

Proper Windows 7 drivers are available for these machines now, as Philip has note. If they're not on the disk, they'll be on Windows Catalog.
The Vista debacle prompted Microsoft to ensure that proper drivers were available for orphaned hardware, like the Sigmatel audio used in many mid-decade Dell models.
