Please download the following driver and install it. As the setup will start you will notice that there is nowhere specified Windows 7 64bit. It's OK as the driver was made for Vista versions, but according to users who posted this link to Dell forums this driver works perfectly in a Windows 7 environment. If you encounter an error while you try to install it, then restart the computer and go to Device Manager locate the audio entry and manually install the driver by pointing the browse window to search for drivers in this location: **C:\Dell\Drivers\R190517**. Once it completes you will have a working audio driver.
