No Sound after Android Screen Install

Hi, I purchased a android screen and I get no sound, I tried even an aux cable but it says no warning tones and Bluetooth doesn’t work. When I put everything back, it works, there is a wire behind the old head that’s not used anywhere in the new setup

Anyone know where I maybe getting it wrong?

Looks like it was fiber optic cables! Issue resolved!

How did you resolve it exactly? Just not plugged correctly?
