No audio at internal speakers on Latitude E6520

Hi,

 

The audio via the internal speaker on my Latitude E6520 is suddenly gone. but the audio is ok with a headset. I deleted everything related to sound on the device manager and scan for new hardwares. I aso did the audio driver update. In the sound properties --> speakers, there is one item that is unplugged. we did not physically open the laptop.

 

OS: windows 7 64bit 

any ideas?

Thank you for your help....there could be different technical names to this problem but you have given simplest fix.

What I did?

1. I played some sound using youtube and tried to poke a stick in headphone jack and it was intermittently playing the sound

2. Then I tried to disable the headphone and even intermittent sound stopped

3. Then I enabled Headphone option and made it my default device and changed setting for Microphone Arrey and Rec Playback to play sound thru headphone and now my speakers are working

I have no idea what is going on inside but I will take it as long as it works and I greatly appreciate you taking out time to write your input on this site.

.there could be different technical names to this problem

Hello. When this issue first appeared 8 or 9 years ago, it was right after manufacturers stopped putting the old AC97 audio codec on the motherboards and started using the then new HD audio codec.

The issue presented 2 contradictory symptoms: the audio would pass the infallible Dell 32-bit Diagnostics, thereby proving it was a software problem, but replacing the motherboard would fix it, thereby proving it was a hardware issue.

I did not have access to a laptop with the problem, so I did a sort of thought experiment and came up with a theory (see the Headphone Jack FAQ) that explained how it could be both a hardware and a software issue, and I called my explanation the Sense Pin Issue, or just a failed sense pin. The theory has never been proven or disproved, but it has stood the test of time and there have been a number of indications that the theory is correct. Probably the name Sense Pin Issue is about as close to a technical name as one is going to get.
