Windows 7: No Sound after XP to Windows 7 Upgrade

A little web searching found this:

ftp://ftp.us.dell.com/audio/ANALOG-D...00_R296215.exe

The drivers are for a Precision workstation, but I expect that they'll work on your Dimension.

Let us know, if you like.

Hi Maranda,

Please share if the driver suggested by 'bobkn' worked for you.
If not, you may also try installing the following driver (Sigmatel R99254 audio driver) to see if that helps: Driver Details | Dell United States

While researching, I came across a similar situation where this driver appears to have fixed the issue; you may want to give it a shot.

For best results, I would delete all audio driver files from the hard drive and try installation again. Please open this location on the 'Hard Drive' c:\Dell\Drivers\R***** and delete any folders whose 'R' names correspond to a 'Sigmatel or Realtek driver'. The Sigmatel folders may have a subfolder named 'WDM'.

The operating system may try to install audio driver with 'already existing files' in the driver folder. That may produce 'error messages' and may block you from manually installing the 'R99254 driver'. After you unpack the files be sure to cancel the installation process. (You may try manual installation in compatibility mode, as suggested in my previous post)

Hope this helps. Do reply with the findings.

Windows 7 Ultimate 64-bit
 
 

I am having a similar issue with an upgrade from XP to 7 Ultimate. My system shows the sound to be working fine, but there is absolutely no sound coming out of, either the speakers, or the headphones.

My computer is a Compaq SR2023WM, with all original hardware. I did an upgrade scan before I did the install, and there was no mention of sound card incompatibility. In fact, every test that I've run, trying to find this issue, has come back negative. Device manager says the sound is kosher, and an attempt to "update" the driver gives me "The best driver..., yada, yada, yada" message.

Is there anything else you need to know about the system to give me any suggestions?
