Solved! sharp tv model number LC42SB45UT,

[Anglean]

I would like to add a soundbar to the TV but the audio output is some prong type inner, there are RCA wires to the soundbar GooDee but no sound comes out of the soundbar. Help, please.

From the pictures the TV has an optical out, the rest are inputs. If you are connecting the RCA wires on the soundbar to the TV, you are using the wrong thing. Connect the optical out to the optical port on the sound bar. If the soundbar has no optical port you will need to get an adapter.
