Where can I get Vostro 1400 Audio Driver for Windows 7 32 bit.
Try installing the Sigmatel HD audio driver. There is not one for Windows 7 so you must use the Vista version and install using Vista compatibility mode.
Download the driver package using the browser, not Dell Download Manager. Extract the files (unzip or unpack) but cancel the installation process. Go to the hard drive to c:\Dell\Drivers\R171786 (This is the folder that is created when you unpack the download. It contains the driver files.)Right click on setup.exe and select Properties. Find the compatibility tab to select Vista.
