These cables have a hexagonal plastic mouth with a small jack in the middle. You can typically find them in tech departments of retail stores, or on Amazon. The PS4 Slim doesn't have an optical audio output port, so you won't be able to use this method if you have a PS4 Slim. The port resembles the end of the optical audio cable. You should be able to find this port on the back of the main speaker unit. If your speaker doesn't have an optical port, you can buy an optical adapter. For example, you would use an optical-to-RCA adapter to connect an optical cable to traditional red-and-white (analog stereo) speaker ports. This port is on the far-left side of the back of the PS4 while facing it. You should be able to hear the PS4 menu music through your speakers after a moment. If you don't hear anything, adjust your speakers' volume.
