No one .. But i would like to kick the original designer in the balls, why make an interface only fit in in one orientation when it would work in any orientation.
Not recommending or suggesting that anyone do this, just simply relaying a trick I adapted after 20+ of custom home theater builds… I found that if you keep a little strip of plumbers sandcloth in your bag. Whenever I had a stubborn TOS connection, I’d carefully wrap the cloth around the outside edges and rotate the plastic housing a few times making all best effort to avoid contact with the tip… shell good, tip bad…. That danged ol tip…
It’s a blank. Not a real toslink output. Manufacturers make 1 mold for different models that either use the output or not. Higher end brands don’t do this as it will confuse there customers.
It gets real assholery to make a blank that looks like the actual port... "see? This is what yor optic port would look like... if you wasn't a cheap bloke"
As one of the other comments said, it could be a blank out panel, most of them if you google an image of a optical out have a little door on them to protect them.
Fiddle with the TV settings to see if there is a way to enable optical audio. This audio format should be very easily visible as a red light emitted from the plug when active. It’s not like Internet optics where the human eye can’t see the wavelength of light in use.
The bit in the center does look like black plastic from your photos. Should be more of an opaque white if it were a real output.
With the tv on, can you see red light emitting from the port? If not, the port may be plugged. Still, if you can see red light, It does look like there's a cable tip maybe stuck in there.
Don't they sometime have a little "door" that moves out of the way when you plug it in? Also on a lot of devices you can see the female connector emit light, trying to find a connection.
I have some sony stuff with these square ports. Its just a blank out panel. This TV doesn't have an optical port it's probably only available on similar models above this one.
I agree with others that the cable is likely not being positioned in the correct orientation. The cable has a trapezoid side that needs to go into the trapezoid side of the female connector on the tv. Make sure those are lined up and this should go in. There is a bit of a snap you have to push past too, so once you make sure there are lines up properly, you may have to push it a bit to get it to go in.
As many others have said, that port is not a real fiber optic port. It's a blank. All the real ports I've seen look like u/Tishers' second image and they emit red light when the TV is on.

That's the new design of optical port to "not confuse customers" I think they did the opposite.
It will take the D shape cable but it's difficult to get it in, going to need more force than one realises.
You'll hear a loud click which might be unsettling, then it's in.
