Latitude E7440 - Sound not coming through headphones

I have the same problem as Elizabeth1579 but it is intermittent.  Sometimes the audio will switch over and sometimes it won't.  The Windows audio indicators say that sound is passing through the system but when my headphones are plugged in, no sound comes out.  When unplug them, the speakers work. Uninstalling and re-installing the drivers every time this happens is not an option.  This should be a main use case for audio drivers and I would like to understand the timeline for an updated driver that fixes this issue.

Thanks.

updated driver that fixes this issue.

I doubt that any of the Dell social media people who are on these boards would have access to that information. Their function seems to be to sell Dell's out-of-warranty service. But there are 4 audio drivers available to you right now (assuming you have 8.1 like Elizabeth1579).

> The Windows native driver -- instructions posted earlier in this thread.

> The current Realtek audio driver.

> The previous Realtek audio driver. Note that if you want to try an earlier version, it is best to first completely remove any newer version. Do it by by finding the Realtek driver in Device Manager under Sound Controllers, right click on it and select to Uninstall, and check the box to "delete the driver software for this device". Reboot and recheck Device Manager. If Realtek shows up again then repeat the process until there are no longer instances of Realtek there, then install an older version.

> Realtek driver direct from the Realtek site.

You can see all of the Realtek versions that Dell supplies for the Latitude E7440 at its HTML page.

The ones with the "WB" symbol in the OS column are the Win 8.1 versions. There are 2 of those and 4 for Win 7 & 8.

I would not be surprised if it works with the native driver but not with one or more of the Realtek drivers, because we have seen this problem on other models with Realtek. I think some of their drivers are not calibrated correctly re impedance sensing and thus failing to detect the headphones. If none of the drivers fixes the intermittent jack issue then I would think it is a hardware failure.

Hello

I have the same issue with one user where the sound work but opn a random basis he lost sound during a call

Hi ,

The information which you have provided is not sufficient .I would ask you to confirm if this issue was seen after any software changes or after system's hardware was replaced .Also do confirm if the audio was heard via speakers.I suspect this to be software issue hence reinstalling drivers should fix the issue,however do send the service tag info ,operating system installed on  the system via private message so that I can check the details to assist you better .

Awaiting your response.

Kindest Regards,

Hi PETE ,

Regret the inconvenience ! But do send in the test reply confirming the status of the system after the jack was removed .

Kind Regards ,

Hello,

I can confirm the audio problems with the E7440. I am an IT Pro and I never had such a painfull audio devices like the E7440. I'm running Win 8.1. I do a full test with different installations and audio driver combinations. Allways starting with a complete new installation from scratch. Nothing has solved the problem. If I switch from one youtube video to an other while on headphones often the audio stop. I unplug the headphone, audio works, replugging no audio. Sometimes it helps to close and reopen the browser (ie, firedfox or chrom, it's always the same). Sometimes it helps to stop the video, waiting 30 secondes an restart. The audio jack is really pain. I rember the times when an audio jack work like a mechanical diversion, good old school stuff.

As a workaround I'm using a littel usb audio device from logitec. It's barley bigger than the headphones audio plug and I have not to confirm any annoying dialog like "do you plugin a headphone or a toaster?"

Best regards,

Andy

Confirm, have the same problem, and I really consider change my laptop. I have never had that problems... It;s sick... :|

This helped me, I had the same problem with Latitude E6540.

That fixed the headphones, but now the built-in speakers don't work.. :(

Thanks anyway.

It's a shame for Dell to have a problem like this in the 21st century with a high-end laptop..

Hey

I have DELL Latitude E7440 and I used headplugs wiht it few days ago. Since then the built-in speakers do not work. Any advice what could be wrong or is there anything I could try? I have tried pluging the headplugs in and out fast, restart, and the installation trick mentioned here above. 

Hope for help!!

Hi Team ,

I was seriously disturbed installing the sound and bluetooth drivers from dell support and downloads to make my bluetooth device entry in playback devices( tried with realtek drivers and the drivers provided by microsoft for windows 7). But none worked

Can you suggest me any driver to play bluetooth device using Latitude E7440.

Thanks and Regards
