It is normally good advice because "No Audio Output Device" usually means that Windows cannot find the audio driver. But Windows 7 has its own basic audio driver that it will normally install when you re-boot if the IDT driver files are missing, so there could be some other problem causing the error.

Restart the computer & tap F12 to run a hardware diagnostic, check the Quick audio test & check if there is audio here, this will confirm the physical speakers are fine. Check the BIOS version installed. For my reference, please click on my Dell username & send a private message with the service tag, registered name & email address. Dell-SreejithR

All of a sudden my sound does not work anymore. i have a Dell Lattitude 3540. Upon further investigation I found the speaker icon is shown with a Red "X", and when I hover the mouse over it, a message of "No Audio Output Device Installed" would appear. T As far as I'm aware there's been no software installed that would have lead to this problem.

When you open the Device Manager and expand the "Sound, video & game controllers" category, do you see "High Definition Audio Device"? If not, then Windows is not detecting the audio hardware on the motherboard. One reason that can happen is that the audio is turned off in the BIOS. Most Dell BIOS do not have a setting for audio, but a few do.
