I recently upgraded to Windows 7. After updating my audio I have seen that it did not work. I tried to update the audio driver, automatically through windows, and manually from the manufacturer's website. I am using an Dell laptop. Window detects the trouble and tries to apply a correction, saying that there is a problem with HD devise. It continues, reinstall the driver may be solve this trouble. But after doing this nothing happen in this. I have tried many solutions which is given on to the Microsoft website but nothing helps me. So finally, I tried to download and install the driver from the dell website, each version for every OS offers. A driver is not available of window 7, only Vista, XP and 2000. Each downloaded drivers encountered an error during installation and could not be loaded. The elaborate audio says its general properties to be developed can not start (Code 10). No updates for the controller design are available. Any idea how to get my sound to work again?
