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.
