To get the best audio from your PS4 System, it needs to be configured correctly to match your audio equipment. In most cases, using HDMI for your primary audio output port ensures that configuration is automatic, and because of that, this is the preferred output port to use on the PS4 System. Unfortunately, there are some setups for which the automatic configuration does not work as expected. Also, if using the optical output, configuration isn't automatic and must be configured manually. It's important to note that these audio configuration issues happen with any equipment, including other game systems, media players, and computers. However, for this guide, the focus is specifically on addressing common audio setup issues to ensure that you're hearing everything exactly as intended on the PS4 System.
