Latitude 7390 audio jack issue

Hello,

I have just setup a Dell latitude 7390 on windows 10, the audio speakers work fine but it does not seem to detect when headphones are plugged in the headphone jack so if I do that, the sound remains on the speakers.

I have tried uninstalling the audio devices from the device manager and reinstalling with the Dell drivers file but it still doesn't work.

All my drivers are up to date with Dell command update.

Any ideas?

Re: Latitude 7390 audio jack issue

The first time you plugin the headphones it should prompt you what you plugged in.  To reset this on your tray click on the blue and white W icon and then click on Maxx Audio Pro.  Click on headphones icon to change the output or reset the popup.  You can change the output here and do some tests. If you click on playback, then you can see you can click to Show pop-up dialog when device is connected.  Try doing it again and then choose the right device when you plugin your headphones.

If you don't have the Maxx Audio Pro running in the tray that could be reinstalled.  We had a problem with an older dell that it would default to "line in" instead of headphones if you didn't pay attention to the popup.

Re: Latitude 7390 audio jack issue

Same issue

Jesus Dell latitude laptops are junk status.

The laptop has been crashing everyday multiple times- Dell saying nothing wrong with the laptop- then last weekend quietly released a software update to firmware for graphics card that has fixed the issue.  

Hate Dell.

 

Now I have noticed after fixing the freezing issue, with the firmware update; I can no longer plug the headphones into the headphone jack and have sound go through the headphones.... jesus christ.

Come on Dell, fix your **bleep** products

Never buying a Dell anything for personal use.  Just too unreliable.  **bleep** I have to use one for work.  Suggesting to my management they move off Dell ASAP

Re: Latitude 7390 audio jack issue

I don't get this prompt at all, I haven't installed anything weird (as this is the PC account without administrator properties) As well as this is a reoccurring issue with nearly two-dozen other identical spec laptops. The audio-jack never worked from the beginning with any earbuds etc., but speakers worked just fine. I tried to contact Dell support, however, I had to leave before I had the problem diagnosed.

 

I'm not too sure at all to what is happening. I have this same issue with my Dell Inspiron at home, but I've lived with this.

 

Side note, with the Inspiron, plugging in stereo speakers works (with a restart) However, plugging in anything else does not work.

Re: Latitude 7390 audio jack issue

I had this very same issue in 37 laptops (7490 and 7390) in my company. After breaking out my head we discovered that the audio jack is much more tight than other laptops, so you have to plug your earphones using a little bit more pressure, until you hear a "click". It solved the problem for us!!!

Re: Latitude 7390 audio jack issue

I have same problem.

It happens at two 7390 so far, but I think there is a possibility that the damage will expand.

So I asked DELL PRO SUPPORT for repair. (Now he is repairing near me.)

But, he can not solve the problem even if the motherboard is replaced....

Re: Latitude 7390 audio jack issue

You can try the following, it solved my audio jack problem in my dell latitude 7390.

Open Task Manager, choose Startup tab, then disable HD Audio Background Process. Then choose Processes, end task HD Audio Background Process,(there are two of them).

Then uninstall Realtek Audio driver. In Device Manager, right-click (or press and hold) the audio driver, and then select Uninstall. Restart your device and Windows will attempt to reinstall the driver.

After the restart the audio jack works fine for my headphones.
