PS4 Controller Audio Issue

I received a wired PS4 dual shock 4 controller as a gift specifically to use as remote control & gaming controller.
I have a Kodi 5.1 Android TV box.

I was told it was “plug and play” and it didn’t matter that I don’t have a PS4.
But while watching a movie or TV show, as soon as I plug the PS4 controller into the USB port, the audio stops coming from the TV and is re-routed to the controller.

So I can only hear the audio if I plug headphones into the controller’s headphone jack.

Has anyone had this issue?
I’ve tried changing a number of Setting with no luck.

I do not have a PS4 console so any solution that includes the console won’t be an option.

Can anybody help? I’m not very technical but I can follow specific directions.
