Inspiron E1505 Speackers not working

A new Sigmatel audio driver for XP systems was released in December.

If that doesn't fix it consider the following as a possible reason:

The Dell laptops like yours with a Sigmatel 92xx audio chip utilize IDT's UniversalJacks technology, which is somewhat complicated. In addition to the usualmechanical parts, the jack also uses current & impedance-sensing techniques totrigger software configuration and switching (to send the audio signal to thespeakers). So there are three areas of potential failure: mechanical, electronic, andsoftware. Sometimes, a little very gentle wiggle of a plug in the jack will get itto resume normal functioning, at least temporarily.  There is a sensing pin inthe jack that is used to detect the presence of plugs and I think that it can be thecause of failure to trigger the software switching.

Normally the audio test in Dell Diagnostics would confirm that there is a hardware problem, but the Universal Jacks can cause a false positive 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 procedure might be to try a new motherboard. In other words, it can be tough to diagnose.

Thanks. But.... I did what you said and sound doesn't work i started movin my computer and i hear sound sometimes so it's kinda like something wrong like you said how do i fix that?

If it is a hardware problem and if you are still under warranty contact Dell about a repair. You will need a new motherboard to replace the jack.

The Universal Jack problem I described occurs in all models with the Sigmatel 92xx chip, not just the E1505. The models with the Sigmatel 97xx chip don't have the same problem because they did not use the Universal Jacks technology.

"I don't know what is going on."

I said that this is a hard problem to diagnose, because the symptoms can mean either a hardware or software problem, and Dell Diagnostics which is usually infallible at determining which one can't be relied on for this one problem. As I said, the way to diagnose this is to replace the motherboard (as a last resort after all else fails). If that fixes it then you know that it was a hardware problem after all. One thing you can try is to wiggle the plug in the jack, or gently insert a q-tip. If that produces any sound at all through the speakers it is an indication that there is a problem in the jack.
