It looks that your Windows is unable to find your sound device. For that go in Control Panel > Sound. In the window under playback can you see the Sound device installed. If not then you will need to re-install it. Click on My Computer > Properties looks for Device Manager. Look for sound devices and under that check that you can see Realtek High Definition Audio or something similar. Is there any exclamation mark on the same. You can right click and click on update drivers. You can download drivers manual from dell site. Click on Support and provide your model number for the right audio driver. There is a tool called as PassMark SoundCheck which can test your audio hardware.
