Windows 10: Why the rear panel "line jack blue" is not working as Rear Speaker out anymore?

It is greyed out and does not give an option to reconfigure like the other jacks. I am running my system in 5.1 ch configuration. I have tried everything like reinstalling the drivers and all. Also, no forum or any community seems to have answer to this.

Rear audio jack not working

I've tested different driver versions but it just doesn't work. It used to work sometime ago but not anymore.

Update: it works with a different headphone but they have the exact same jack, and the one that doesnt work in the rear jack works in the front jack perfectly

On the sound control panel it says not plugged it

 

Rear audio jack not working

Hi mysticBTW.

Do both sets of headphones function correctly when plugged into the front audio jack?

Could you post a closeup pic of both of the headphone plugs, side by each and identifying which one doesn't work when plugged into the rear audio jack?

 

Windows 10 Realtek Audio rear analog jacks not working

I just upgraded to Windows 10 from Windows 8.1, and found I wasn't getting any audio from my speakers. My Realktek HD Audio manager can detect my analog speakers hook-up in the rear panel. I can hear audio from my front panel analog jacks with my regular
speakers. I tried updating the audio drivers to 6.0.1.7541 from the Realtek site but still could not hear anything from my rear panel analog jacks (the front still work). Changing the frequency also did not work. (edit 8/2/2015) I went into sounds and checked
properties for speakers/headphones, the default device. (edit 8/7/2015) It lists the front panel l/r jack and the rear panel l/r jack, along withthe other surround sound jacks (l/r rear, center sub, l/r side).
