Laptop speakers wont play sound at all. Try running the audio tests in Dell Diagnostics. These interactive audio tests are designed to narrow down the problem to either the software or hardware. The tests are independent of Windows and drivers, meaning it doesnt matter if those are working correctly or not. To run Dell Diagnostics. Restart the computer and tap the f. Select Diagnostic from the boot menu. The computer will run its pre boot assessment tests PSA before Dell Diagnostics starts. During the PSA you will hear some tones through the system speaker but this does not adequately test the audio hardware. Dell Diagnostics plays an instrumental piece of music complete with drums, so if you only hear some tones then you have only run the PSA.

Select Custom, then the audio tests. At this point after you have opened Dell Diagnostic custom if you cant find the option to select the audio tests that is a symptom of a failed audio chip. The tests will run. Alternate between using headphones and listening to speakers in case only one signal path is working. The tests will play some audio and ask you whether you heard it. If you dont hear the music during the test it definitely means there is a hardware failure somewhere in the system. In this case Dell will repair the computer if it is still under warranty. If you do hear the audio during the test but not when you boot back into Windows, that almost always means the hardware is okay but there is a problem with the audio driver or with Windows. Error codes If you answer no to any question that the test asks you, the test generates an error code that can tell a Dell technician that you answered no to that question. The test does not know the exact component that has gone bad. Before answering no to a question, make note of the circumstances at that point so you will know in general what the error code means.

Audio Drivers For Dell Inspiron 1420' title='Audio Drivers For Dell Inspiron 1420' />The Dell laptops with 9. HD audio utilize IDTs Universal Jacks technology, which is somewhat complicated. In addition to the usual mechanical parts, the jack also uses current impedance sensing techniques to trigger software configuration and switching to send the audio signal to the speakers. So there are three areas of potential failure mechanical, electronic, and software.

Sometimes, a little very gentle wiggle of a plug in the jack will get it to resume normal functioning, at least temporarily. There is a sensing pin in the jack SenseA pin that is used to detect the presence of plugs and it can be the cause of failure to trigger the software switching. Skype Launcher 1.4 here. Failure of the sense pin usually results in the computer behaving like there is always a plug in the jack. Normally the audio test in Dell Diagnostics would confirm that there is a hardware problem, but the Universal Jacks can cause a false result in Diagnostics. That is because Diagnostics operates in DOS, outside of Windows, so a Windows software misconfiguration is irrelevant to the test even though in this case it is caused by hardware. So the audio test can pass in Diagnostics, correctly signaling that software configuration is the immediate cause of the problem, but missing that a hardware problem, the bad jack or sensing pin, is the root cause. In these instances the only reliable diagnostic procedures are to try a new motherboard or to use PC Restore called Factory Image Restore in Vista to restore the computer to its original configuration as shipped from the factory. If the speakers still dont work after PCFactory Image Restore then there is definitely a hardware problem even if it passes the normally infallible Dell Diagnostic audio test.
