No Sound in Dell Vostro 1400 and Win 7 ultimate(3 posts)
This is due to the driver issue. you need to install the audio driver in your PC. If you are using the Realtek high definition try to install the driver from the link below.
once the page opens select any GO option near to "Vista, Windows7 Driver(64bits) Driver only (Executable file)" and install in your pC.
This Realtec Warning is IMPORTANT.
"Audio drivers available for download from the Realtek website are general drivers for our audio ICs, and may not offer the customizations made by your system/motherboard manufacturer. To be sure you obtain the full features/customizations provided in your original audio product, please download the latest drivers from your system/motherboard manufacturer's website."
Be carefull of what you install because you do not know the Hardware which is on an OEM motherboard !!!!
