I cannot say with 100% certainty but I can tell you what often happens:-
A case seller designed a case and listed its spec in the product page. Then, after a batch or two, he changed the design but did not go back to update the product details. Instead, he just added a new pic or two. Some sellers would add a disclaimer clause saying that the details are subject to have minor changes without notice and ask a buyer to contact him for final spec before ordering.
So, I think the case, which you are interested in, comes with 2 USB 3.0 ports on the top panel (like what is shown on most pics of the product) + no audio ports + the front panel does not have any port. This might be the current configuration as well because the latest pics are of September 2019. And it is only mid Oct now.
I suspect, the '2 USB ports + 2 audio ports on front panel' is a much earlier design.
If I am not mistaken, all the pics in the buyer feedbacks show this current configuration.
Since often a case would have minor 'improvements' or 'changes' without notice, it is best to contact the seller for confirmation if the location and the types of available I/O ports are crucial to you.
