Front headphone jack broken, how do I use the back panel for my headphones?

[PeraRajkovic]

My front panel headphone jack is broken, so I wanted to use the back panel for my headphones and got a 3.5mm male to female extension cable. But when I plug it into the "Center/Subwoofer Speaker Out" jack, I don't have any audio. I disabled "Mute the rear output device when a headphone is plugged in" in Realtek Audio Manager, and I still don'y have any audio. Does anyone know how to fix this issue?

Okay I literally fixed it just by restarting my PC, never mind.
