Windows 10: Audio Driver - Dell Latitude 7400: Headphones Works for the first time only in 3.5mm Audio Jack

Hi,


I am using windows10 and my laptop is Dell Latitude 7400.


Since the day 1 my audio driver doesn't work properly. When I use my headphones in 3.5mm audio jack, the head phones works for the first time ONLY after the fresh driver update. If I remove them from the audio jack and insert again, the audio only can be listened form my laptop speakers and not from headphones. So if I uninstall the audio driver and install, then again the headphones works for the first time and this loop keep repeating.


I already tried all the recent Realtek audio drivers, updated but nothing solved since last 8 months. Any solutions...........?

How to disable audio jack detection Dell e7400 Windows 10

I have a Dell e7400 (Win 10, 64bit) with broken headphone detection. The headphones are normally supposed to turn on when they're plugged in. However, i need to restart my computer with the headphones plugged in to have it detect the headphone and play sound via the audio jack.
I've tried updating the audio drivers many times wihtout luck.

Therefore I'd like to control this feature manually and force the sound to come out of my headphones all the time.

I've found registry keys that can be edited for Windows 10.

1. Press Windows Key + R.
   
2. Type regedit, press Enter.
   
3. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{4D36E96C-E325-11CE-BFC1-08002BE10318}\0007\GlobalSettings.
   
4. Right-click the REG_BINARY EnableDynamicDevices, click Modify, and set it to 0.
   
5. Reboot.
   

I did not have the REG_BINARY EnableDynamicDevices in ' \0007\GlobalSettings', however, it was in '\0013\GlobalSettings'.
After changing to 0, and reboot, no difference.

I've read somewhere that this might be because my machine is still using the realtek driven and i would need the original windows 10 audio drivers.
"High Definition Audio" (native driver). Source: (https://www.dell.com/community/Lapt...nd-not-coming-through-headphones/td-p/4639683)

However, i've tried uninstalling the Realtek driver without succes and cannot find the windows driver for Dell e7400 on my machine/online.

Does anyone know how to get rid of the Realtek driver and/or change registry setting that even with realtek driver audio jack detection is turned off?

 

Headphone Jack not working (Windows 10, Dell)

Thank you for writing to Microsoft Community Forums.

1. Have you tried using different headphone or speaker on your computer?
   
2. May I know the make and the model of the headphone you are using?
   
3. Are you able to hear the audio from rear jack?
   

You can try troubleshooting below to further narrow down to the root cause of the issue.



Please check the audio cable connection and volume settings before troubleshooting.



Method 1: Enable jack detection.

1. Open Realtek HD Audio Manager.
   
2. Uncheck Disable front panel jack detection from the
   Connector Settings from the right pane.
   

Method 2: Reinstall audio drivers.



I suggest you to download the audio driver from the motherboard manufacturer website and install it.



If you still face the issue, reply to this post with the requested information.
