Most of the laptops that originally had this diagnostic have had their hard drives wiped or replaced, so the diagnostic is no longer available. In a case where there is no audio from both the speakers and the headphone jack, if the audio tests in Dell 32-bit Diagnostic fail then the audio hardware has failed, not an audio driver or configuration issue. Its usefulness for audio was that it could separate out a hardware problem from a software problem. Dell no longer includes it with the laptops.
