Sound not coming from rear outlet

[dmr91]

Hello,

For some reason when i plug speakers into the rear of my Gigabyte B550 Aorus Elite Motherboard no sound comes out however if i plug it into the top of the tower where there is another audio outlet it works fine.

Not sure if this is a software of hardware issue.

Thanks

Output devices below, I thought it was the realtek output but somethings gone wrong.

Realtek HD Audio 2nd Output is for the AUX on the top of the tower.
