Why when Earphone is plugged in the headphone front panel, its shows a converse status?

Question

Problem

• When AUDIO port is not connected to Motherboard (not using headphone front panel)

  • When I plug in the Earphone at the rear panel -> rear panel has sound (everything is fine)

• When AUDIO port is connected to Motherboard (try to use headphone front panel)

  4 cases::

  • When I plug in the Earphone at the rear panel -> no sound; Realtek shows rear & front panel is plugged in

    

  • When I plug in the Earphone at the front panel -> no sound; Realtek shows nothing is plugged in

    

  • When I plug in nothing -> no sound; Realtek shows front panel is plugged in

    (so, it shows the converse status:

    if I plugin the front panel -> shows front panel is not plugged in;

    if I dont plugin the front panel -> shows front panel is plugged in)

    

  • When I plug in the Earphone at the rear & front panel -> rear panel has sound; Realtek shows rear panel is plugged in

    

Question

Why such Converse status (behavior)?

How can I use the Headphone on the headphone front panel properly?

(Is this an hardware problem? (ie: it just my headphone front panel is broken?))

Using:

• Realtek HD Audio

• Win10

Answer 1

Solution

Disable front panel jack detection - in Realtek HD Audio

• (now the headphone front panel should always be on (doesnt change when you plug in Earphone or not))

• (no idea why)
