Download the Sigmatel R99254 driver. Unpack it but cancel the installation process.
It will unpack the files and store them in a folder on the hard drive at c:\Dell\drivers\R99254, and that folder will have a subfolder named WDM.


Open Device Manager and expand System devices near the bottom. Find the PCI Device entry with a ? next to it (or if that is not there then look for "Multimedia Audio Controller") . Go to the properties and choose to update the driver. Choose to manually find the driver and don't let Windows look for it. Browse to c:\Dell\drivers\R99254\WDM

Reboot and it should detect some new hardware and one of them should be the Sigmatel.

if you go to Microsoft update catalog http://catalog.updat...arch.aspx?q=idt enter in Sigmatel you'll find a list of drivers to chose from.

Sorry for the late reply -- I did not not see your question last week when you posted.

The problem arises because Windows 7 does not have a native audio driver for AC97 audio (AC97 is the out-dated type of audio hardware that is on the motherboard of the Latitude D510). As a result, you have to manually install a Sigmatel audio driver, but because the Sigmatel company went out of business before Win7 came out there is not a Sigmatel driver explicitly for 7. The following instructions should allow you to install a Sigmatel AC97 driver into 7:


Download the Sigmatel R99254 driver. Unpack (unzip) it to but cancel the installation process.
The files should  unpack to a folder on the hard drive at c:\Dell\drivers\R99254, and that folder will have a subfolder named WDM.


Open Device Manager and expand System devices near the bottom. Find the PCI Device entry with a ? next to it (or if that is not there then look for "Multimedia Audio Controller") . Right click on the name and select "Properties", then choose to update the driver. Choose to manually find the driver and don't let Windows look for it. Browse to c:\Dell\drivers\R99254\WDM.

When you restart the laptop Windows will detect some new hardware and one of them will be the Sigmatel.

go to Microsoft update catalog....enter in Sigmatel you'll find a list of drivers to chose from.

I found a list of about 2 dozens downloads there and selected the one that seemed closest to the Sigmatel R99254 driver. When I downloaded it all I got was a small (254 kb) cabinet file -- no .exe or setup file. So I see 2 problems for the average person who just needs to download a driver:

1. You can't tell which of the 2 dozen downloads is the right one for a particular model, and

2. There is no obvious way to install it.

For most folks it is probably better to just get the normal Sigmatel drivers from Dell . Note that the Sigmatel R99254 is the correct audio driver for 15 old Dell laptop models that have AC97 audio, but there are 23 other old models that use a different Sigmatel driver, the R90698. See section 9 of  the Laptop Audio Driver FAQ for a complete list of which models go with each driver, and links to the drivers.
