I have a headphone jack with a broken sensor. The headphones are normally supposed to turn on when they're plugged in. Because the jack is broken, however, my computer only detects that my headphones are plugged in when I push or tilt the plug, and that's the only time I can get sound out of them. 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 7 and 8 which give this functionality, but none for Windows 10.

Realtek's HD Audio Manager has a "Disable Front Panel Jack Detection" option which gives this functionality, but Realtek's skin for Dell motherboards, which my computer has, does not include this option.

So I was thinking: Perhaps this Dell skin is only cosmetic. If I could find out which registry key is changed when someone else checks the "Disable Front Panel Jack Detection" box in their Realtek Audio Manager, I could edit that same key on my computer, and achieve the same functionality.

Does anyone know which key this is?

  • Did you try the drivers directly from Realtek? I've had similar issues where the MS-supplied drivers had a clipped interface. Replacing with the ones from Realtek fixed all issues. – Tetsujin Apr 1 '17 at 12:09
  • Yes I did. As best as I can figure based on my research, the UI you get depends on the motherboard you have. If that's not actually the case, I'd love to know. – Strill Apr 2 '17 at 12:38
  • I don't know, both machines here have the same mobo, ASUS. Both defaulted to a crappy MS control panel rather than the shiny colour one with individual speakers distances, EQ curves etc. Swapping to the proper one from Realtek fixed them. – Tetsujin Apr 2 '17 at 12:42

I figured it out! I don't know for sure if this will work for everyone, but it worked for me under Windows 10 while using Microsoft High Definition Audio Device Driver version 10.0.14393.0.

  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.

Windows will now display your headphones as an available audio device, whether you have headphones plugged into the jack or not.

To undo this change, repeat the previous steps, but set EnableDynamicDevices to 1

  • This one works great even without the full-fledged manufacturer driver. Great ! – AMDG Feb 13 '18 at 14:35

    The index value, after the class GUID will vary according to your system specifics; search through them looking for the one with the DriverDesc of "Realtek High Definition Audio". – Lawrence Dol Sep 6 '18 at 23:06
  • Also, you need to have admin privileges – Lawrence Dol Sep 6 '18 at 23:11
  • moved to 0008 after recent update – cnd Apr 22 '19 at 4:25
