No Audio on left Headphone plugged at the front panel

[visualfx]

Hello,
I have no sound on the left speaker of my headphone when it is plugged at the front panel.
when plugged rear it works.
when plugged headphones into the desk speakers logitech 2+1 it works.

my desk speakers logitech 2+1 are plugged at the rear panel it works fine.
when I plug the headphones at the front I get sound only from the right speaker of the headphone.
System newly setup with all drivers.
win 7 pro, asus z 77-a, 8gb ram, i 5 3570, directx 11
I have changed front panel audio connector settings from hd audio to AC97 and vice versa.

I would appreciate it very much if anyone have an advice, as I do long gaming sessions after everyone is asleep and I cant hear from desk speakers at night, not to make all neighbours and family upset.

Internal audio connection inside the case is probably not connected to the motherboard properly.

hi,
this was the first what ı checked. the pins are intact nothing broken, connector plugged until to the end. but does anybody know how to test the plug. ı mean besides that there is no sound from the left

Hi if one of both deskspeaker and headphones plugged back work properly.
if one of both plugged at the front panel, only sound from right speaker either deskspeaker or headphone.
checked by using slider in realtek audio menu.

To check the plug you'll need a volt meter to check fro continuity.
Or just replace the plug.
