In addition to the manufacturer's driver, in Windows Vista and 7 there is a basic audio driver which lacks some functions of the normal driver but does provide audio. Can't say the name of yours because the driver varies according to which operating system you are using and there are usually several different versions of the driver for each OS. The name of the folder is not "Sigmatel" but begins with an "R", such as R171788 or R171789. If you did delete the files then they would be in the recycle bin in their folder. If you uninstalled an audio driver but did not delete the files then the driver would have been disabled but the files would still be on the hard drive.
In some lines Dell now uses hardware and drivers by Realtek and by Conexant.Īnd also, why cant I view that deleted material in my recycle bin? Later it was bought by a company named IDT so now many of the laptops have IDT audio hardware and drivers. If you still have no audio at this point, look at the "No Audio" FAQ for further options.īasically, what I want to know is, whats the name of the standard audio software/ sound card brand used for these laptopsĪt the time of your laptop the brand was Sigmatel. After unzipping the installation should automatically begin. Unzip the files to the default location that will be suggested by the unzip wizard. Expand the 'Audio' category and download the audio driver named "Sigmatel-driver". Go to the Driver & Downloads Home Page and follow the links (or use your Service Tag number) to select your laptop model and its operating system. If that does not get the audio working then download a new audio driver package from your computer's driver downloads page. In Vista and 7, type "System Restore" into the Start menu search box, and then, in the list of results, click System Restore. Choose a date before the problem first occurred. In XP, go to Start>All Programs>Accessories>System Tools>System RestoreĪnd tick 'Restore my computer to an earlier time'. Using System Restore will not delete any data files. Sometimes reverting back to an earlier Restore Point can fix a "no audio" problem.
Windows System Restore backs up certain system files (exe, dll, etc) and also backs up the Registry and many drivers. You might have un-installed the audio driver, in which case using System Restore should restore it.
